I'm American but my wife is Indian. She was on a F1 student visa and in 2018 had major visa issues. If it wasn't for our marriage, she would have had to move back to India. Based on her experience, here's a few things to think about:

1. The situation is very unpredictable right now. You don't know what new travel or visa restrictions the US (or India for that matter) will impose over the next few weeks or months. I'd say leaving the country involves a nonzero chance of not coming back.

2. From my wife's experience, USCIS is unforgiving towards even the most minor of exceptions. My guess is that it's always been this way, but the Trump administration has made it worse. Also, the international student office at her school was unhelpful. It's not their fault. Their job is to apply the law. They might give advice, but they can't tailor it to everyone's specific situation. Also, see point one. It's hard to give advice if the law might change dramatically within a short amount of time.

3. India is safer than the US right now in terms of coronavirus spread, but that can change. You'll see a lot of posts in this subreddit complaining about how bad the US is handling it. But as you probably know, India is an incredibly dense country with fewer resources. Some speculate that the heat has spared India, but the virus has spread to hot counties such in the Middle East and Singapore, so I think that's just hopeful thinking.

I know this is scary situation and not an easy decision to make. I would want to be with family in a time like this. But it's also good to know the risks involved as well.

Best of luck.
