Foreign nationals visiting the United States will need to either obtain a U.S. visa or a visa waiver. The visa application process usually involves submitting a form and passport-style photograph online, paying a non-refundable fee as well as attending an embassy appointment for applicants aged between 14 and 79. The visa waiver application process is conducted entirely online and requires less applicant information and does not require applicants to attend an embassy appointment. This article will review some of the common U.S. visa categories as well as discuss the U.S. visa waiver called ESTA.
