a few questions before mailing I-129F

[Jimbo_in_GA 17]

hey folks! hope you don't mind answering a few questions, I'm just worried about the details in my forms to submit with the K-1 visa app. ok, here goes, would the following cause the USCIS to reject my application:

My fiances first name is "Mary Jean," I told her, that's two first names, you can't have two first names, but then she showed me on her birth cert. and her id, AND her passport, sure enough, her first name is indeed Mary Jean. on the forms associated with filing for the K-1 visa would the USCIS have a problem with two names being in the first name box?

My fiances place of birth is, and is stated on her birth cert. as "Musuan,Maramag, Philippines" that looks like two cities to me, is this something the USCIS might have a problem with?

On MY birth certificate, my mother is listed as being born in "Scott County, TN" but she was born in Oneida, TN (which IS in Scott Co.)and my father, oddly enough just says "Mexico" but he was born in Albuquerque, NM. how should i put it down on my G-325A?

thanks guys!
