sorry to hear about your mother's health situation. I am just giving you advise from my heart. Given the situation, the last thing right now you should worry is the immigration crap. you don't need any visa to go back to your home country. Forget about this visa business for time being and take the first flight to see your mother. that is the most important thing in world. Your h1/h4/gc and all that you can do once again as you got your whole life for it.
Hope she recovers soon.
Long time reader of the forum, first post. My mother is very ill and she is in India and I need to go to India soon. Here is the situation, My wife is on H1b and I am on H4. We have not left the country so we don't have visa stamps in our passports. We both have the I-797 approval notices. Mine was f1 to h4 after we got married.
Now can I go to Canada and get my H4 stamping done instead of India, I feel there is a better chance in Canada than India. Does my wife (principal applicant) needs to have her H1 stamped on her passport. If I need to do it in India, what documents do I need, do I have to go the consulate or I can come to USA and at the Port of entry they will stamp.
