Haven't received NOA2 yet, but trying to plan ahead.

Thanks.

I'm not quite sure what you're asking here, but I'll take a stab at it.

Do you mean how long is the greencard/visa good for?

If, by your interview date, you have been married less than 2 years, you will be given a CR-1 conditional green card; the condition being that it is only valid for 2 years. (You will need to file an I-751 to remove the conditional status.)

If, by your interview date, you have been married more than 2 years, you will have an IR-1 green card, which is valid for 10 years.

ilovemyfrenchie,

Until they decide that you've abandoned it when they realize that you're not following through and responding to their instructions for taking the next steps. Could be years.
