General Visa Information
The sites http://www.unitedstatesvisas.gov and http://travel.state.gov have information about obtaining a visa for those traveling to the United States. Both sites have links to websites for U.S. embassies and consulates worldwide. The embassy and consulate websites have very helpful information about procedures, timelines, communities served, required documentation, and fees.
