EB1B杰出研究员或教授申请的限制

There are some restrictions for EB1 Outstanding Researcher or Professor petition.

The first restriction is the "academic field". The U.S. Citizenship and Immigration Services (USCIS) regulations define the term of academic field as "a body of specialized knowledge offered for study at an accredited United States university or institution of higher education."

The second restriction is the "permanent job offer". The term "permanent" in reference to a position means "either tenured, tenure-track, or for a term of indefinite or unlimited duration, and in which the employee will ordinarily have an expectation of continued employment unless there is good cause for termination."
