In order to make the April 1st deadline we had to file our i-600 form again.This time unfortunately we only had about 1 day notice. We scrambled to get our copies of our birth certificates, marriage certificate and homestudy together. DH was out of town until Tuesday night, so we got our cashier's check and FedEx'd the package Wed morning.
So we should be set for another 18 months! Again!
