It is all correct. Wife working in GZ waiting for the I-130 get processed. We are doing it the right way albeit a lonnnnng way- nine months and changes with no RFE. As far as I know getting married in the States then left for the CR-1 is perfectly legit.
Got the I-130 approved by USCIS. In the process of filing for I-485 for the wife. Would it be appropriate to file the re-entry permit I-131 concurrently with I-485? The instructions was a little vague. Happy New Year!
