I'm going to travel abroad. When I apply for a passport, I have a mole on my nose, which can be seen in the passport photo. If I drop it later, will it affect my exit?

It shouldn't affect it. If the visa officer or the border control staff have problems, just explain the reasons. If you are worried, you can also issue a certificate, just be prepared! Follow-up: Thank you. Should I go to my hospital in Dot mole to get a certificate or go to the exit-entry administration of the public security bureau (that is, where I get a passport)? Answer: It should be done in the hospital, and visa officers may not ask this question to relax.
