I have a question, when 1 has the removal proceeding terminated without prejudice based upon approved I-130 and pending I-485. So what happens now?

Your immigration file should be transferred to USCIS for processing of your Form I-485. You should be contacted by USCIS for an interview. It can take several months for an interview to be scheduled. You can always schedule an infopass appointment of you wish to follow-up the Form I-485. You can read more about adjustment of status at http://myattorneyusa.com/adjustment-of-immigration-status.
