Because of the high level of interaction between the countries of the world we are interconnected today, each country needs diplomatic departments, such as embassies and consulates, to help and allow this interaction to take place. The ambassador is the government representative of their country’s affairs between the two countries. These offices also serve potential immigrants and international travelers. Although the terms of the embassy and consulate are often used interchangeably, the two are different. The embassy is larger and more important than the consulate, and is known as the permanent diplomatic mission, usually located in the capital of a country. For example, the US Embassy in Canada is located in Ottawa, Ontario. The capital cities of Ottawa, Washington, DC and London each have nearly 200 embassies. The Embassy is responsible for representing the country, dealing with major diplomatic issues (such as negotiations) and safeguarding the rights of its citizens abroad. The ambassador is the highest official of the embassy and serves as the chief diplomat and spokesperson for the internal government. Ambassadors are usually appointed by the highest level of their own government. In the United States, the ambassador is appointed by the President and confirmed by the Senate. Usually, if a country recognizes that another country is a sovereign state, an embassy will be established to maintain diplomatic relations and provide assistance to travel citizens.
