Being your category CR1/IR1, it can currently last from 17 months to 35 months in that center, but since you are in the immediate category, it may be less if the case is clean and not complex. Now you can make an expedited request with your congressman or senator so that USCIS, if you meet the requirements, can expedite your case and approve it before, In my office we have achieved approval in less than 4 months using the expedited so it is a good and valid option if you don't want to take so long.

14 - 18 months

mine took almost a year. Vermont

@Joe Jr after filling i130, our lawyer filed i129F almost immediately and seek for it to be expedited but we received a reply denying our expedite. Do you mean we can expedite the i130 too?
