My father came to US on visitor visa last week. At the port of entry, he was not asked about how long he will stay and the officer stamped an expiry date on 26th Aug 2012 on the I-94. however, my father has a return ticket of 30th August 2012. My question is, how can I get the date changed on the I-94 so that my father does not become illegal for 4 days. What are my other options?
Thanks a lot in advance.
