To answer your questions :
1) The time until her swearing-in ceremony depends upon the local USCIS office. Some offices swear-in new citizens right away, whereas for others it could be a couple of weeks before a swearing-in ceremony is organized.
2) Your green card application can be submitted as soon as your wife has her certificate of naturalization (which she’ll receive the day she becomes a citizen).
3) Processing times vary at each USCIS office. In Upstate NY, both the Albany and Buffalo offices are taking approximately 6 months to schedule green card interviews.
4) My fee for a marriage-based green card application is $1,500.
