I am a GC holder and recently got married. I e-filed my I-90 to get the last name on my GC changed to my new married. Been almost 5 months now since I filed and the only thing I've received so far is the Receipt Notice. Anyway, technically I'm still using my maiden name in almost everything. (DMV won't let me change last name on driver's license unless I get GC changed) Since it's taking them forever to process my I-90, is it advisable to file for the N-400 in my maiden name and have it changed later OR wait 'till I get the I-90 taken cared of before I file my N-400. If I do choose to file my N-400 while I-90 is in progress, will that lengthen or complicate the processing of my N-400?
