I have an IR-1 interview at Montreal scheduled for February 20. My passport expires November 20, 9 months later - so as I understand it, there is no problem on the consulate side as it is still valid for >6 months.
However, I'm wondering if there is an advantage to renewing my passport ahead of time so that way the visa stamp is in my new passport and remains with me when I travel for the next 10 years? Or does it not matter, because what really matters is the physical green card?
