This is not accurate. The PR must have been married to a USC for a period of 3 years in order to qualify for expedited naturalisation, 3 years rather than the mandated 5 years for all aliens. See Section 316 versus Section 319 of the INA.
Apologies if I gave incorrect information I did not mean to do so. However, could you clarify this for me further because I am rather confused by your statement? It may be because I am looking at it through the eyes of a CR1/K3 applicant who is married to her husband but not residing in the same country.
I believed that 316 required that the couple met the "lived together in marital union" criteria i.e not just married for at least 3 years but LIVING together for those 3 years IN the US. Is this not correct?
From my understanding, in my case, we will be married for almost 4 years and living together for 3 of them when I start considering/am eligible for naturalisation.
For a K1 visa, the date of living together will start up to 3 months before the marriage
For a K3 visa, the marriage will start before living together in the US
The IR1/CR1 visa would be married before living together in the US
So would it be correct to say that the date is the day when both begin happening? How do you prove a date like that? You can prove the day you marry with a marriage certificate but how do you prove the day you start living together? Would it not be the day you enter the US on whatever VISA you arrive on?
