This question already has an answer here:
I am doing my 1st year Master's degree in Biotechnology. I got selected for the Khorana Program for Scholars conducted by Indo-U.S. Science and technology forum, to do a 3 months internship at a U.S. University.
I have enough reasons to come back to India as I have to complete my Master's degree after returning so that I can apply for higher studies. There was a personal fund mentioned in my DS-2019 that is to be provided by my U.S. mentor as scholarship. I explained this in the interview. I didn't get any questions or asked for any documents to show my tie to my home country, although I brought everything with me.
What should I do next time to avoid visa rejection? Should I have provided them all the documents even if they didn't ask for it?
