first B1 , Then F1 visa for my Fiancee,

Dear Pjang and other expert/nice person,

my fiancee now is a student in Canada , she will transfer to US in the coming June.

Maybe when she come to US , after we get married. I will file my 140/ 485 (NIW category) , from this forum, if we get married too soon , the later 485 is not easy approved .

my thought : let her get B1 visa firstly come to US for travel, and back Canada , Then she will apply F1 visa . does this approach is better??

thanks so much for your answer.
