Question for Green Card

[immihelp]

Hi,

I would appreciate if you could let me know how do I find how many years are left on my completion of H1b visa (which is valid for 6 years)
The visa left is counted from the day my H1b was approved or the day I came to USA. Is it mention on my I-797 paper what is the date of expiry.

Thanks,

You can't find anywhere like that.

From the day you entered the US.
