Glad the question was answered.
Spousal applications take longer.
Fiance (K-1) is the quickest route. We did ours 6 years ago, took 4 months for approval, then another 2 months waiting on Medical Exam and Consulate Interview.
When you get married, go immediately to the local USCIS office to file the paperwork.
Definitely expect to spend atleast $1000 on the process.
