It depends. If the Principal Applicant (in H-1B, L-1A, or L-1B status) reenters the U.S. pursuant to a valid Advance Parole document, he/she will be paroled into the U.S. Any dependent family members with pending adjustment applications who had been maintaining H-4 or L-2 status will not be permitted to reenter the U.S. with a valid H-4 or L-2 visa stamp following travel outside of the U.S. Such dependent family members must use a valid AP for re-entry to the U.S.
Dependents using an EAD for employment are not considered to be maintaining their nonimmigrant visa status and must use an AP for travel.
If a dependent enters the U.S. pursuant to an AP document, such entry as a parolee does not affect the Principal Applicant’s ability to enter the U.S. in H-1B, L-1A or L-1B status provided that the Principal Applicant has maintained valid H or L status.
