Visa Ineligibility / Waiver
The immigration laws of the United States, in order to protect the health, welfare, and security of the U.S., prohibit the issuance of a visa to certain applicants. Examples of applicants who must be refused visas are those who: have a communicable disease, or have a dangerous physical or mental disorder; have committed serious criminal acts; are terrorists, subversives, members of a totalitarian party, or former Nazi war criminals; have used illegal means to enter the U.S.; or are ineligible for citizenship. Some former exchange visitors must live abroad for two years. Physicians who intend to practice medicine must pass a qualifying exam before receiving immigrant visas. If found to be ineligible, the consular officer will advise the applicant of any waivers.
