jjoseph,
There shouldn't be any US immigration problem with your wife having her passport in her maiden name. My wife, who was a K3 and is now a LPR having adjusted status, used my surname starting with my petitions but has not changed her passport and does not intend to.

Hi, I am an USC and I filed (I-130 & I129F) for my wife using my last name instead of her maiden name. Her passport is in her maiden name, so does she have to change from her maiden name to my last name in her passport or can she keep her maiden name? I know that the embassy will issue the K3 visa using her passport name. I am just wondering would there be any problems if we decide to keep her passport in her maiden name even though I sent all the forms (I-130 & I129F) using my last name. .....
