A visa allows you to travel to the United States as far as the port of entry (airport or land border crossing) and ask the immigration officer to allow you to enter the country. Only the immigration officer has the authority to permit you to enter the United States. He or she decides how long you can stay for any particular visit (usually 6-12months). Immigration matters are the responsibility of the U.S. Department of Homeland Security.
Millions of foreign visitors travel to the U.S. each year. Others come to live here permanently. International visitors and immigrants add greatly to the nation's cultural, education and economic life. As a citizen of a foreign country, who wishing to enter the U.S., must first obtain a visa, either a nonimmigrant visa for temporary stay, or an immigrant visa for permanent residence. The type of visa you must have is defined by immigration law, and relates to the purpose of your travel. Yet, based on law, not everyone will receive a visa to come to the U.S.
General, in order to be eligible to apply for an immigrant visa, a foreign citizen must be sponsored by a U.S. citizen relative(s) or by a prospective employer. Unlike most other immigrant categories, Immediate Relatives are not subject to numerical limits under immigration law. Major immigrant categories are: 1) Immediate Relatives, 2) Special Immigrants, 3) Family-sponsored, and 4) Employer-sponsored.
Also U.S has 2 categories visas for : immigrant and nonimmigrant.
Immigrant visas are for people who intend to live permanently in the U.S. Nonimmigrant visas are for people with permanent residence outside the U.S. but who wish to be in the U.S. on a temporary basis. The reason can be for tourism, medical treatment, business, temporary work or study, etc.
Usually, it’s easy to get a visa but after the terrorist attacks of September 11, 2001, U.S had made some changes in our laws governing visitor entry and exit. Now require additional application forms and security clearances. Visa applications take longer to process. For example, many applicants experienced hardship when applications got backlogged and delays became indefinite. Fortunately, U.S. has improved the visa clearance procedures. Better interagency cooperation and automated procedures have speeded up the clearance process.
