What should I do if I forget to give a medical examination CD when I enter the country with an immigrant visa?

First of all, compare the process of entering the US Customs for inspection, so as to find out how to deal with your problem:

1. Holders of immigrant visas or green cards must submit their passports, immigrant packages delivered by consulates (unauthorized opening is prohibited) and filled-in customs declaration forms to the citizens/residents inspection desk on the plane to CBP.

When you check your luggage, you have to hand in the customs declaration form and documents. If the customs requires unpacking inspection, you should take the initiative to cooperate and unpack the inspection immediately. Don't doubt that the customs officer motioned to pass, and immediately put forward the luggage to leave.

According to American law, although the customs officers have no right to open your luggage without permission, if they ask you to open it, you can't refuse. CBP has the right to open your luggage. Any contraband found in the luggage will be confiscated on the spot.

So in contrast, if your whole process is well coordinated with the customs, it means it is recognized. Don't worry about the CD.
