If you need a Visa to enter the US please apply for one as early as possible. Visa applications are now subject to a greater degree of scrutiny than in the past. For many applicants, a personal appearance interview is required as a standard part of visa processing. Additionally, applicants affected by these procedures are informed of the need for additional screening at the time they submit their applications and are being advised to expect delays.
Starting October 1, 2003, each Visa Waiver Program traveler must present a machine-readable passport (MRP) at the U.S. port of entry to enter the U.S. without a visa, otherwise a nonimmigrant visa is required. Additional information can be found on the U.S. Department of State Bureau of Consular Affairs Visa Services Web site.
