We have previously confirmed that – if you currently have a valid visa in your original passport – you do not need to get a new visa simply because you got a new passport. The good news is that you should keep your old passport with the valid visa and and present it along with your new passport when you enter into the United States. Of course, since nearly everything is complicated about immigration law, here are some additional key things to keep in mind if you're traveling with both your old and new passport:
- Make sure your visa is the correct type for the purpose of your visit to the US (for example, you cannot use a visitor visa to conduct business in the United States).
- Confirm that your original visa is not damaged, is legible, has not expired, and will not expire soon. A CBP officer may not allow you into the country if your visa will expire within a few weeks or so.
- When you are inspected at the United States port of entry, and if you are admitted, your new passport will be stamped and the following special code will be added: "VIOPP" (visa in other passport).
- Keep in mind that it is a bad idea to try to take out your visa from your original passport and add it to your new passport. Attempting this will invalidate your visa.
- Finally, both your new passport and your old passport must be from the same country and must be the same type of passport (for example, you cannot have a diplomatic passport and a regular passport and hope that a CBP officer will accept this.)
