I have a scheduled visa appointment on 23rd June. Please advise me regarding how to answer "how can u show that u will return to India after completing ur MS in US"?

If you have family you are wanting to go back to they are good reason to return. Providing them with a statement of home ownership in India would be good reason. Retrn ticket? Any of those are signs that you are here for education but that you have wishes to take your education back to your homeland and better your community there.
