My husband is a Seyed. We did all his paperwork with "Seyed Mohammad" as his first name.  I think as long as you pick a way and stick with it throughout the process, you'll be fine.  I chose that way because all his documents from Iran listed the Seyed.
 
P.S. -- Feel free to contact me directly with any questions you have.  I'm happy to pay-it-forward.
