Should be no problem, but you will have to put together a sh*t ton of evidence to convince the interviewer that your marriage is bona-fide since your husband filed your 485 only after a month of your marriage. Anything that shows that you had been in relationship for say 10 years. Anything that proves the authenticity of the relationship, not mere for sponsoring 485. May be your account is joint or you had been living together, bought a car together, etc. Hope this helps.
