Answers: What types of documents and fees are required to process my U.S. visa

Prospective immigrants seeking a green card and other foreign nationals intending to enter the United States must obtain a visa. This applies to both temporary nonimmigrant visas and immigrant visas which serve as the entry document for a new permanent resident. A fee and the presentation of specific forms and documents are usually required. A local immigration attorney can provide more information about the paperwork and charges that must accompany U.S. visa and residency applications.
