If I show a letter from my current employer stating they will rehire me after my studies, will that help reduce the chance of US visa rejection?

Yes, a letter from your current employer stating they will rehire you after your studies can strengthen your US student visa application. This shows strong ties to India and your intention to return, which visa officers look for to assess non-immigrant intent.

However, this letter alone does not guarantee approval - your overall profile, financial documents, academic plans, and interview performance are also important. Including the letter is helpful, but it should be part of a well-prepared application.
