Hello ,
I am asking a quesiton on behalf of my Ex.
My Ex is Thai but lived 25 years in Germany and have 2 kids with German passport and 2 with thai (one of them is mine - i am Danish)
She moved to Thailand with her former boyfriend and her Residence card expired.
My question is now, how would she go on to get back to Germany when she has German national kids , is it possible to renvew a expired "Aufenthaltstitel" if not what visa should she apply for when she has German kids? , she only has contact with 1 of the fathers (former boyfriend) who is a german living in Germany.
