♦ TN visa

The TN nonimmigrant classification permits qualified Canadian and Mexican citizens to seek temporary entry into the United States to engage in business activities at a professional level.

You may be eligible for TN nonimmigrant status, if:

• You are a citizen of Canada or Mexico;
• Your profession qualifies under the regulations;
• The position in the United States requires a NAFTA professional;
• You have a prearranged full-time or part-time job with a U.S. employer (but not self-employment – see documentation required below); and
• You have the qualifications to practice in the profession in question.

TN签证的持有人可以为多家雇主同时工作。但是每一个雇主 （原申请入境的雇主除外）必须提交I-129的申请。并且，只有当递交的I-129申请获批后才可以为该雇主工作。
