I'm physically challenged(handicapped) & single & have to go to US on L1 visa. I'm wheelchair bound & need my parents to come alongwith(you can say as an escort). In this regard have some queries:
1.Is there any visa other than B2(Visitor) visa which can be used for my parents?
2.What is the maximum duration for B2(visitors) visa? Can this be extended on special grounds because of my disability.
3.What if my parents complete the full term of B2 (visitor) visa & come back to India & immediately return again to US in the same year, will a fresh term of 6 months start again?
