I know this is an older post, and the OP probably has this info. by now. But just in case anyone else needs to know, to be specific about the CR1 visa, it is for spouses who have been married less than two (2) years. After the two-year mark, you would be getting an IR1 visa (for those married 2 years or more).
Also, the CR1 is a conditional visa, meaning that you must adjust status after the period runs. An IR1 visa is a permanent, 10-year visa. No need to adjust status.
From what point is the two years measured, the date of the initial application, the immigration date, or something else?
