To clarify, my question was about getting the 10 year vs 2 year conditional visa. If we're married at least 2 years when the visa is issued, then she would receive the IR 10 year visa. If it's less than 2 years, then she would receive the CR 2 year visa. If the process is going to be close to the 2 year mark, then we might want to slightly delay things to avoid removal of conditions. But it was hard to find at what point in the process they determine the 2 year anniversary mark and 10 year or 2 year visa. Eventually I found that they use the date of US entry.
