Question related to my parents visa

[Lakshmi Kumar Dabbiru]

Hi,

I want to get my parents to US. We are two brothers. I did my masters and working here on H1B now. My brother works for an indian company and now in US on a L1 visa and my sister-in-law is pregnant. My father is government employee still left with 2yrs of service and my mother is housewife. I have few questions.

1) Who should sponsor the visa for my parents? I think my brother might be right fit as he is on L1 and he has a need.
2) If visa gets rejected for some reason, in how much time we can reply again?

Thank you.

1. It does not matter.
2. At any time. However, if there is no change in the situation, it is harder to get it next time.
