The importance of the Embassies & Consulates in each and every country does not begin and end with a mere representation of the sovereignty of the home country in a foreign land or to be a part of the trading activities between the nations. In this age of economic globalization, when the entire planet has turned and is getting more and more into a global village, naturally there shall be also an escalation of inter country visits be it for business, official reasons or mere pleasure trips. Thus a foremost duty of the Embassies and Consulates is to remain engaged in the sorting and grating of passports and visas to the required people. Almost all countries now require visas from the non-nationals that wish to enter their territory. Generally Visa restrictions are imposed to control the crossing of borders by foreigners. However, a visa does not permit entry. It is a mere document that indicates the applicant’s passport and visa application have been reviewed by a consular officer at an embassy or consulate of the country he/she wish to enter, and that the officer has determined that the concerned individual is eligible to enter the country for a specific purpose.

The Visa allows one to travel to the destination country up to the entry point of the destination country through airport, sea port or land border crossing where the immigration officer has to be asked to allow you to enter the country. In many countries only the immigration officer is liable to permit the foreign national to enter. He or she also happens to be the key person to decide how long one can stay for any particular visit. There are various different rules and regulations among the countries regarding the visa requirement. For example, in USA if any citizen of a foreign country wishes to enter the very individual has to first obtain a visa, either a nonimmigrant visa for the temporary staying or an immigrant visa to fulfil the deisre for permanent residence. The first job he/she has to do is to communicate with the US Embassy in his or her home country. The type of visa that should be obtained have tobe defined by the immigration law relating to the purpose of the visit.
