Travel and Visa ban for Nationals of Particular Nations: Advisory and Tips

Given the broad phrasing, even if you are not nationwide of the above nations, but you travel there, you might be disallowed from entry into the U.S. If you have currently taken a trip abroad to one of these countries, then you might be barred from the U.S. throughout the 90-day duration.

Claims have been filed to challenge the travel ban, following are some suggestions for dealing with this restriction if you fall into any of the above categories:

Consult with your immigration attorney.
For permanent residents, do not sign a Kind I-407. By doing so, you will relinquish your residency.
If your prepared journey is a discretionary one, then consider delaying it until the courts have ruled on the travel restriction issue.
Even if you are not nationwide of any of the above countries, but you have taken a trip to any of them, the CBP might still try to disallow your admission.
Note that even if you do not fit into any of the above categories, you will still likely be screened and if there is some problem in your record, the Customized and Border Security (CBP) might position you in secondary or deferred assessment.
