Miss D, I did not change my name (and likely won't). We filled out all of the paperwork with my maiden name (i'm the sponsor) and as far as I can tell, that has been the least of our worries. There was no mention of it in our notes or in hubby's interview. If you do decide to take his name, I would do that later once he is here and it will be a cleaner process! you have enough going on! That is my 2 cents, take it with a grain of salt

PS - Congratulations on your marriage, I'm sure it was a beautiful ceremony and hopefully, everything you hoped it would be. I have a very good feeling about your upcoming application considering the feedback you all received after your first interview.
