If I change my name on my passport, would it affect my chance of?
If the process by which you change your name is fully legal in your home country, and you can provide the relevant documentation to support that, then it will not be a problem. If you just get a new passport under a name that you have never been known by (which Im not sure is even possible), then it might. How are you going to prove that you are the same person who was granted the original visa?
