I have never run across this before and all the reference material online take me to ICE websites or other immigration services. My borrowers first name on his Driver's License is "UNK" and on his Perm Res Card is "FNU". Where ever he came to when he first immigrated combined his first and last name into his last name. Example in DL: Last Name: John Smith; First Name: UNK
What do I use for his first name on the mortgage loan application? Anyone run across this before?

Are you selling the loan? If not, what difference does it make. If you are - check with your investor.

Yes, definitely selling. Thanks RL.
