My mother-in-law is an australian citizen who is suppose to have an interview on sept. 10, 2009 for her us immigrant status but she went back to australia yesterday. Without a parole visa, can she return to US using visa waiver program to attend to her interview? she stayed here in the us for almost 15mos, can she return as a tourist within a mos eventhough she already has a pending change of status application? what are the risk involve? we really need to know this ASAP so anybody here who can help will be greatly appreciated.
