I am currently employed with one of the Government Services Company here in US and in status of H1B. I am planning to sponsor my brother for his undergrad studies. Is it a good idea for an applicant to show that he/she is sponsored by his brother? There are lots of rumors that it is not a good idea to reveal that siblings who have gone to US in F1 are not coming back and working there. Does anyone have any experience sponsoring your siblings? Any info would be greatly appreciated.

well, it is always good idea to tell truth about siblings if they are in usa.  I was here and when my sister applied visa, i asked her to tell the truth in the interview if they asked her about me.  she had no problem getting visa.  however, i was not sponsoring her studies in usa.
