A diplomatic mission is a representative office of a national government located in another nation's territory. There are two main types:
- An embassy is usually in the capital city at the destination country; its main function is to deal with all diplomatic government-to-government issues. If there are trade negotiations to be done, or if one government wants to complain about some action by the other, the embassy handles that. If an official delegation from one country plans to visit the other, the embassies will make the arrangements.
- A consulate can be located in any (usually major) city and provides consular services for individuals or businesses. They can usually provide visas for foreigners planning to visit their country. For their own citizens, they provide passport services as well as birth registrations, marriage registrations, and various other sorts of advice or assistance. If you are in business and need advice about local regulations, your consulate is a good source.
Many embassies also provide consular services; that is, they can also do everything a consulate can. There are some exceptions in countries where the capital city is not a major city; for example, the US embassy in Canberra, Australia, does not provide consular services, but there are consulates in the larger cities of Sydney, Melbourne and Perth. In other places, some embassies maintain a separate "consular section" location to provide consular services in the capital city of the host country. Sometimes the services are split up somewhat differently; for example, the Canadian High Commission in New Delhi provides most consular services but there is a separate office for Indians wanting a visa.
In some cases, one country's diplomatic mission may be assigned to process visa applications on behalf of another. For instance, in Singapore, the Danish embassy processes visa applications for all the Nordic countries, even though Sweden, Norway and Finland all operate their own embassies in Singapore. Similarly, British embassies often provide consular services on behalf of many Commonwealth countries that do not have diplomatic representation in the host country.
Visitor registration services
Most nations have a system that lets a citizen who is abroad long-term register so that their home government has a record of their presence. For many countries, you can do this online but for some you may need to actually visit a consulate. Registration is generally not needed for tourists except in high-risk areas, but it is recommended for anyone working abroad, studying abroad or retiring abroad.
Registering will usually get you on a mailing list that brings email notifications from your government; these are often rather boring, but some are useful or interesting. This can be very important in some circumstances; for example, if a war or epidemic breaks out, your country's mission may be the best source of information and aid. Registering can also be very useful if you need services from your home country, for example being able to vote in an election back home or wanting to ensure that your health insurance there remains valid.
Help from consulates and embassies
These missions may provide a variety of services, which usually include:
- If you lose your passport or it is near expiry, they can arrange a replacement. For many countries, processing time is several weeks.
- If you lose your passport and have time constraints, they can arrange for a temporary replacement in order for you to be able to head home. Even this usually takes a few days.
- If you need a visa for the country they represent, they can issue that.
- If there is an election back home, they may be able to help you vote remotely. If not, they can at least provide advice on the procedure.
- If you have a child abroad, they can register his or her citizenship and issue a passport.
- The missions provide most of the information that their home governments base travel advisories on. Talking directly to a mission may get information that is more detailed or more up-to-date than the advisories.
- In the event of unexpected war or serious civil disorder, embassies may arrange evacuation flights for their own citizens and sometimes others.
There are also services which become relevant if you want to marry:
- If you marry abroad, there may be special procedures to get a visa for your spouse.
- If you are engaged, some countries, such as the USA, have a special fiancée visa; others, such as Canada, do not.
- If you want to marry abroad then some countries, such as China or the Philippines, require a document from your country's mission certifying that you are single. The mission may require that you produce documents such as a divorce decree or the death certificate for a former spouse before they will issue their document; it is not uncommon for these requirements to delay a wedding, and in some cases the foreign partner may need a trip home to get the documents.
- You can sometimes get married in an embassy, which is useful where a local wedding would be expensive or difficult, or when neither partner is from the host country, or for a same-sex couple if the host country does not recognize such unions but one of the home countries does.
Details vary a lot from country to country. All missions will charge a fee for most or all these services.
Travellers should not expect too much from their country's missions abroad, though this does vary both with where you are from and where you are visiting. Most missions do not have staff or funding for various things you might think they should do.
- If you are broke and stranded, they generally will not fly you home, though most will contact family or friends for you and provide a channel for them to send money.
- If you have a serious accident or illness, they should help to ensure you can receive suitable medical attention or repatriation. If you die, they can contact your family (provided you filled out the emergency contact space in your passport or gave contact info when you registered with them) and may help with arrangements. They will not pay the costs of these services.
- If you are jailed, they may visit, provide a list of reputable lawyers and/or translators that can speak your own language, and can inform your family if you wish, but they are quite unlikely to provide a lawyer or translator, pay for one, or post bail.
- Diplomatic missions generally do not interfere in the judicial process of the host country, even when their citizens are accused of serious crimes that are not particularly serious (or even a crime) back home. Generally speaking, they will support you in identifying legal representation and raising objections if the local due process is flouted (for example, confessions extracted by torture). Even if they do ask the host government to release you or show leniency, the host government is under no obligation to do so. Some countries such as China and Indonesia have executed foreigners for crimes such as drug smuggling.
- People with dual nationality (see Passport) are often considered by host governments to be local citizens and therefore not eligible for consular support from another country. The diplomatic mission can still try to help, but what they can do will be limited.
If someone takes your passport for any reason except visa processing (for example an employer who wants it "for safekeeping" or a rent-a-whatever place that requires it "as security") this is not allowed under international law and, at least in theory, your consulate can ask the host government to lean on local law enforcement to ensure its prompt return. If this fails, the consulate is best-placed to add the document to lists of stolen passports and issue a replacement.
Embassy or consulate events
In addition to providing those services, the missions give fine parties and may invite any citizens who are about. Diplomats tend to live rather well, with good stocks of booze (even in countries where alcohol is illegal except for diplomats), excellent cooks and good supplies of imported foods. In particular, they often have the specialties of the home country; for example, a Russian mission will usually be well provided with caviar and vodka.
Of course, most of their parties are only for other diplomats, local government officials and other important people; the average traveller will not be invited, though a visiting business person or journalist might be. However, they also host celebrations on their national day or other important holidays — for example, Christmas or Thanksgiving for Americans — and almost anyone with the right passport can be invited to those. If you are abroad at such a time, it is certainly worth asking. An oddity about this is that the more out-of-the-way the place is, the better your chances are. An embassy in a major capital may already have its guest list filled, but one in Back-of-beyond-istan is very likely to welcome visitors.
Missions may also sponsor or assist with cultural events to promote their country. For example, the Thai Embassy in Ottawa works with a local Thai immigrants' association to run an annual Thai Festival. Many governments also have organisations to teach their language abroad.
Complications and variations
There are a number of complications and variations, which will only occasionally matter to travellers.
Some of the smaller or poorer nations have few missions abroad. To get a visa for Tajikistan, for example, you may have to go to a major center like Moscow or London. New York is also good for this since almost every country has a mission to the UN. The bright side is that in these cases it's often possible to apply by mail, although this means letting go of your passport for several weeks.
The reverse can apply as well. If you are in an out-of-the-way place and need consular assistance, your country may not have an embassy there so you might need to contact another mission; for example, most visitors to Bhutan would need to contact their embassy in Delhi. Alternately, your government may have an arrangement with some friendly country by which that country's mission will also provide consular service for citizens of your nation; this is most common for pairs of countries in some international group such as the British Commonwealth, the ex-Soviet CIS or the European Union. This is one more thing to check when planning a trip that goes far off the beaten path; your own government's foreign affairs department is the best source of information on such arrangements.
Some countries' missions have a system of dividing the destination country up into zones and requesting or even requiring that people use the consulate for their zone. In China, for example, Canada will tell someone in Wuhan to use the Beijing embassy and someone in Fuzhou to use the Guangzhou consulate, even though the Shanghai consulate might be more convenient for both. Typically, this does not apply to tourists, only to people living in the country, but it does apply to both locals and expatriates.
An honorary consul can be located anywhere and provides very limited consular services. Often the position is granted by a foreign government to a person with business interests in that location; they may not even be a citizen of the country they represent. For the traveller this may be of use for notary services (such as the signing of legal documents), and if you are in jail or hospital they might visit and contact the consulate for you. However, they are usually not authorized to grant visas or issue passports.
In addition to embassies and consulates, there are diplomatic missions that use other names for various reasons:
- A mission from one Commonwealth country to another is a High Commission.
- A mission from any country to the United Nations is a Permanent Mission.
- A mission from the Vatican City to any country is called an Apostolic Nunciature.
- A mission representing a non-sovereign entity (such as a province or federated state) is a delegation; its activities are classed as paradiplomacy.
- Countries that lack worldwide formal diplomatic recognition may still deploy embassies under another name. Taiwan has "Taipei Representative Offices" or "Taipei Economic and Trade Offices" in many countries.
- Countries which have been split into multiple entities (such as the former East Germany and West Germany, or current-day mainland China and Taiwan) may use non-standard terminology to avoid recognising the "other side" as a truly foreign country. For instance, Cold War Europe had "permanent missions" headed by "permanent representatives" representing one Germany to the other in the 1970s, while the Chinese now speak obliquely of "cross-strait relations".
- Where direct diplomatic relations have been terminated, an interests section in a third country's embassy may be the only formal representation. Direct US-Iranian diplomatic relations ended abruptly in 1979; Pakistan is now the protecting power for an Iranian interests section in Washington, DC.
In at least 90% of cases, all a traveller has to know is how to find the nearest embassy or consulate — the one for the destination in his or her home country to get a visa and the one for his or her home at the destination for help while abroad.
Unless you are travelling with a special diplomatic passport (issued only to diplomats or their family members), then diplomatic immunity does not apply to you. If you do have official diplomatic status, then it becomes a more complex legal question and your employer should be able to provide expert advice.
Employees of international organisations are typically covered by a separate and different set of rules. Soldiers posted in foreign countries are not considered diplomatic staff unless they are assigned directly to an embassy, such as military attachés or the US Marines who guard most American embassies.
Diplomatic missions have special status under international law.
- An embassy is considered entirely under the control of the sending nation, and local laws do not apply inside it. For instance, police from the host country may not enter the embassy compound without permission from the sending nation. A consulate does not enjoy this privilege, and local laws do still apply.
- A few relatively senior diplomats are immune to arrest or prosecution by the host country regardless of the crime, whether for spying or more mundane offenses, and the only option is for the host to expel them. The assassination of Kim Jong-nam in Malaysia is one of the more infamous examples. Some mission staff may have only a weaker "consular immunity"; they cannot be prosecuted for anything done on the job, but can be for other things. Honorary consuls are not entitled to any diplomatic or consular immunity. While a diplomatic mission can waive immunity, it is not required to do so.
- Diplomats' luggage or things shipped in a "diplomatic bag" are immune from customs inspection, although there have been instances where customs officials simply ignored this restriction.
- Some cars have diplomatic license plates, usually a conspicuously different colour than other plates and/or with a specific alphanumeric sequence. For example in Ottawa, these plates are white-on-red and have "CD" (from French corps diplomatique) as the first two letters. They cannot be stopped for traffic violations and in some places some of them flagrantly ignore "no parking" signs. This is particularly noteworthy with United Nations diplomats in New York City.
- Diplomats are usually exempt from taxes imposed by the host country; some missions to London insist that city's "congestion charge" is a tax, which they refuse to pay.
- People travelling on diplomatic or official passports typically have different visa requirements from those travelling on ordinary passports.
- Children born to diplomats abroad do not obtain the citizenship of the host country as a birthright, even where jus soli is otherwise offered unconditionally.
- Reciprocity is often required as a baseline for respect, and a good deal of diplomacy is basically tit for tat. If members of a representative country's diplomatic staff refuse to pay parking tickets then the host country will likely instruct their staff in their corresponding mission to do likewise. Expulsion by the host nation of another nation's diplomatic staff may well result in their staff being correspondingly expelled. This can extend to visa policy for standard travelers, with fees and requirements often demanding the same treatment between two countries.
There are a set of rather complex rules covering how far these protections extend. Not all embassy staff have diplomatic privileges but some staff outside the embassy — for example, at a trade mission or an aid agency — may. Diplomatic immunity typically only applies in the country you are accredited to, and would usually cease to apply if you travel to another country outside your official capacity.
