For those debating the CR1 vs the K1 here's some info:
K1 visa (Fiance(e) Visa)
Typically takes 5-8 months until you can move to the U.S.A. This is typically sooner than the CR-1 visa.
You'll have to qualify financially to sponsor.
You will have to have met in the last 2 years from the date you filed.
Fees are greater in the long run.
Once you're in the U.S.A. and married, you'll have to file for an Adjustment of Status (AoS) to get a green card (GC).
If you want to work while waiting for your GC you'll have to file for your Employment Authorization Document (EAD) or work permit and your Advance Parole (AP) with your AoS, this can take an additional 3-6 months before the EAD and AP is granted (will not effect the AoS processing).
If you've been married less than 2 years when you are granted your AoS you'll have to apply to remove conditions in 2 years, which is additional fees and paperwork.
CR-1 Visa (Spousal):
Can take upwards of a year before you can move to the U.S.A.
You'll have to qualify financially to sponsor.
Fees are less in the long run.
Once you enter the U.S.A. you get your green card and can start working immediately.
If you've been married for more than 2 years at the date of entry to the U.S.A. on a CR-1 visa you will not have to apply to lift conditions.
Check the Administrative Processing for your country to get a better idea of a timeline.
