I have I-797 for (for H1B) from other employer. can i apply for B1 from my current employer? I did not get the stamping yet.

Will it effect my H1B?

will there be any rejections for B1/H1?

Would my current employer get to know about my i797 form?

It shoudn’t be a problem, but you may want to consult with an attorney.

P.S. This is not a legal advice, this is my opinion.
