Many of my clients have asked me, “What happens if the Customs & Border Protection makes some type of declaration on my status?”
It is important to remember that the CPB and the USCIS are two completely different entities. This can sometimes lead to confusion.
For example: If you enter the U.S. on a B-2 visa, and the Customs & Border Protection stamps on your passport “No COS”, “No AOS”, or “No EOS”, you can STILL make a lawful application based on a bona fide marriage to a United States citizen to apply for your adjustment of status.
Just because CPB stamps that, it does NOT mean that USCIS will adhere to it. These are two totally different departments, and one does not have jurisdiction over the other.
