Few questions

[immihelp]

hii have a following queries please if you can clarify :

1. I had applied for a tourist Visa but got a valid B1/ B2 ( Regular)
Visa for 10 years.
Had been to US for Tourist purpose. But now since I have that Visa
Can I go to US through my current employer on this B1 Visa. Also if I
go then what will be the max duration I can stay in US.

I need to work on a project in US for around 8 - 10 weeks.

2. If I apply for a L1 blanket Visa to visit US, will the B1/B2 visa
will be cancelled or it will still be valid?

Please if you can answer my query asap.
Will greatly appreciate your reply.

1. Yes, you can go.
Duration of stay is determined at the port of entry. But 8-10 weeks should
not be a problem.

2. It would still be valid.
