While pending parents I-130 in US can they travel out of US

The difficulty here is that your parents’ visiting visas require nonimmigrant intent, and they could have a problem reentering the country if they are questioned by a CBP officer on that, Probably the best solution is for your parents to file I-485 applications and obtain I-131 advance parole documents to travel in and out of the US during the time of processing. I note that advance parole applications are taking time for USCIS to process, and so your parents may not be able to leave for possibly 5-10 months after filing. I-485’s are only filed in the United States. If your parents wish to process their papers overseas, they would do it on form DS-260 immigrant visa applications.
