Immigration legal matters

Federal immigration law determines whether a person is an alien, the rights, duties, and obligations associated with being an alien in the United States, and how aliens gain residence or citizenship within the United States. It also provides the means by which certain aliens can become legally naturalized citizens with full rights of citizenship. Immigration law serves as a gatekeeper for the nation's border, determining who may enter, how long they may stay, and when they must leave.

The Immigration and Nationality Act provides a yearly minimum of 140,000 employment-based immigrant visas which are divided into five preference categories. They may require a labor certification from the U.S. Department of Labor (DOL), and the filing of a petition with United States Citizenship and Immigration Services in the Department of Homeland Security (USCIS).

The cost of each immigrant visa application processing fee (per person) is (US) $335. Fees must be paid for each intending immigrant, regardless of age, and are not refundable. Local currency equivalents are acceptable. Fees should not be sent to the consular office unless requested specifically. USCIS charges additional fees for filing petitions.
