Start your visa application early – If you need to obtain a visa at a post abroad, plan ahead.  Most consulates are very busy during the summer and holidays, and appointments may not be available on short notice.  Visit www.usembassy.gov and familiarize yourself with the procedures of the post including documentation requirements.  You can learn about visa wait and processing times at the State Department’s Travel Information website. Please note that these times are only approximate and subject to change.
