Urgent - Visa transfer just approved, flight in 2 days, no I797

Hello. I just got approval of my visa transfer, checked through USCIS site. I have flight in 2 days to join my current company in US. I am now eligible to join new company, but I am not sure how I can travel without I797 document which I can get after a week or more when hard copy is sent to my new company and then to me?

So my question is, can I travel to US for new company with old I797 and visa stamped? How I can convice POE officer why I don’t have I797 from new company but still want to go there?

FYI, I never traveled to US and I got visa transfer from India.
Please reply fast, flight in less than 2 days.

Buddy dont be in a hurry wait till u get the new I797 .
If you travel on the old visa stamp and old i797 but for new employer
Then it is illegal…
If anything goes wrong then u cannot enter US in your life time as they will
Ban you to enter US for ur life time…
So i will suggest you to wait for few days till you get the new I797 and then u travel…

Ok thanks for your comment. Do i need anything else other than original I797 from NEW company?

Your offer letter, your job description documents if any and if you have a client letter carry that as well.
