If you plan to work or reside at your destination, check with that country’s Embassy or Consulate in the U.S. to learn about any special documentation requirements (such as work authorization or a residence visa). A listing of foreign embassies and consulates in the U.S. is available on the Department of State’s website at http://www.state.gov/s/cpr/rls/dpl/32122.htm. Foreign embassy and consulate contact information can also be found on the Consular Information Sheet for each country.
