Request a Letter of Invitation for U.S. 签证

A citizen of a foreign country who seeks to enter the 美国 (U.S.) generally must first obtain a U.S. 签证, which is placed in the traveler’s passport, a travel document issued by the traveler’s country of citizenship. Certain international travelers may be eligible to travel to the U.S. without a 签证 if they meet the requirements for 签证-free travel.

有一个你.S. 签证 allows you to travel to a port of entry, airport or land border crossing, and request permission of the Department of bet9九卅娱乐ju11land Security (DHS), Customs and Border Protection (CBP) inspector to enter the U.S. While having a 签证 does not guarantee entry to the U.S., it does indicate a consular officer at a U.S. Embassy or Consulate abroad has determined you are eligible to seek entry for that specific purpose.
