In 1999, USCIS regulations were changed to permit certain H and L nonimmigrants with pending applications for adjustment of status (I-485) to depart the United States and return without first obtaining advance parole documents. Those same regulations included a rule that never made much sense: It required the H and L travelers to present not just their valid H or L visas to the inspector at the port of entry, but also their original I-485 filing receipts. Though rarely enforced, the rule was nevertheless in effect, and was a cause of concern, particularly since it often took weeks for a receipt to arrive. Many were reluctant to travel without the receipt in hand.
By regulation issued in November 2007, the USCIS eliminated the I-485 receipt requirement, bringing a measure of relief to H and L travelers. As a result of the rule change, H and L nonimmigrants with pending applications for adjustment of status, who maintain their underlying nonimmigrant statuses and travel on their valid H or L visas, no longer have to be concerned with whether or not an I-485 receipt has yet been issued, and even if it has been issued, they can travel freely without bringing it with them to present to the inspector at the port of entry.
