Question

Your mother is from another country; you of all people should be sympathetic to immigrants. what Match the fallacy with its name.

Answer 1

I think the answer would be : Ad hominem

It's a form of argument whcih directed to a person based on his/her position that they're into or the personal relation that he/she has within the argument
In this case,  this argument will not be viable if her mother is not an immigrant

hope this helps
