H Visa

I came to the US in Aug 2015. Completed masters in 2017. Started OPT on 07/2017. When applying for OPT EAD I joined employer AZTech Technologies. I joined as an intern and was there for like 4 months. He responded for 2 months during training, after a couple of months employer did not respond at all. I got a doubt and found another job and moved to a different company. Later I got an H1B and I 140 approved. I am planning to go to India this August 2023. Recently I found out through social media that the company I joined in the initial stage of OPT EAD was a black listed company. Most people who joined those similar companies' visas got rejected when they went for stamping. I am going for H1B stamping. Will there be a problem in my case? Could you please advise me in this case? In an emergency situation, I need to go to India. I heard from some friends and social media groups out of my research that I can go get stamping done in other countries and then travel to India and can be back to the US. 

I got my H1B visa approval recently and I have got my stamping date in May. My company is going through a bad phase financially and has had 2 layoffs (might do another layoff in next few months) I go to India for stamping and get laid off before getting my visa stamped (Can I come back to the US with 60 days left? Can I get my visa stamped if my company pays me for another month or so considering that my last day is a month later? Can I get my visa stamped even if my last day has passed)I go to India for stamping and get laid off after getting my visa stamped (can I come to US and do my job search) If I get laid off while in India but have an offer letter from another company (H1B transfer done/ transfer to be done after returning to US)
