Most people from Iran, Libya, Somalia, Syria, Yemen, and North Korea (and certain government officials from Venezuela) are indefinitely banned from obtaining most immigrant and nonimmigrants visas to the U.S. There is no exception for people trying to unite with U.S. citizen or lawful permanent resident spouses, children, or parents. There are no longer exceptions for qualifying “bona fide relationships.”

Muslim Ban 3.0 includes a waiver provision; a “waiver” is permission to get a visa, even though the Muslim Ban says you are not eligible for one. Waivers are available to people who can show that (1) denying entry to the U.S. would cause the visa applicant undue hardship, (2) entry to the U.S. would not pose a threat to the national security or public safety of the U.S., and (3) entry would be in the national interest of the U.S.

The ban does not affect lawful permanent residents (“green card”–holders), dual nationals traveling with a passport from a non-banned country, and a few other minor exceptions.
