JoeF is right
My parents got a 6 month visitor\'s visa in end-November. They finally decided to come in
mid-May next year( a few days before the expiry). However, at POE, they got a I-94 that allowed them to
stay until November ( 6 months).
Also, if you want to extend their stay past the date stamped on their I-94, you can
file an application at the INS to extend their stay. It takes a few months for the INS to
process this application. INS usually grants these applications, and it is legal for them to
stay until this application is adjudicated, even though their I_94 has expired.
Your praents can also get a 10-year visitor visa from the consulate. However, that still
doesn\'t affect their period of stay. That is decided by the date stamped on their I-94 at POE.
