Any one knows how to extend the immigration visa expiration date? Please let me know! THANK YOU!!! My parents got the immigration visa finally. It took them 5 years to go through all the non-immigrant visa and immigrant visa process. They bought the plane tickets and were going to come to states in Nov 21th. But just yesterday I heard that my mom was found cancer!! Just two weeks before they plan to come here! I don't know what I should do now. If we can extend the visa for another half a year, my mom will get the operation this week and stay in China for chemo before coming here! If she come here, I am afraid it will take too long before she is even able to get the opration and I am not sure what all the insurance policies are!! Their visa will expire in december! I called the US embassy in guangzhou and only got a fax number. I sent a fax to ask and haven't gotten back any info. PLEASE, PLEASE, PLEASE help!!! Thank you guys in advance!
