How can I replace the visa stamp of my minor children on renew?
Stop! Dont do that! It is illegal for you to replace the visa stamp. It is considered tampering with an official document by an unauthorized person (you). What you are supposed to do is carry both the new (childrens renewal passport) and the old pp with the visas. Present both to the US CBP Officer at the port of entry. If all goes well with the friendly officer, ask how you can join the 2 passports. 1. Rubber band the 2 from the center page of each passport. Or 2. Staple the back cover of the new passport to the front page of the old passport. Do not tape over anything. Do not paste or tape over any printed or stamped pages. Any moved visas, or covered pages could invalidate both the passport and the visa. As far as websites to replace the stamp, Im not sure what you are referring to, maybe youre asking about getting another visa of the same type. That would cost you another application fee. You already have a valid visa. Dont apply for a second duplicate visa.
