Do I need to use B1/B2 in the future too? (after overstay)

[Help needed 0]

Hi,

I have one quick question and hope someone can help me.

I have record of 2-month-overstay on my student visa due to H1b application denied. I was just trying to pack everything back after the denial.

I have a business trip coming in 2 weeks so I went to apply for B1/B2 at US consulate. It was a bit difficult since I'm from a VWP country and they questioned why I overstayed and stuff but I passed. Today I received my passport with 1 month U.S. B1 visa (June 3 - July 2).

It has a notation on it:

IBM
Raleigh, NC
June 15, 2013 to June 29, 2013
B1 in lieu of H1b

what does that B1 in lieu of H1b mean? I am going to attend a training and salary will be paid in my home country (this is written on my invitation letter). Will I get into any trouble when I go through CBP?

Also, after this business trip (I hope this trip will help to clear my record a bit?), if I want to go back to the U.S. for travel in the future, can I use ESTA to enter the states? (I applied ESTA before I went to consulate interview and my ESTA did get approved)

Thanks for your opinion!!

There is no time-frame as when you can use ESTA or not after overstay.

As per regulation after overstay one is not allowed to use VWP anymore and everytime they want to travel to US they have to apply in person.

You can try ESTA for or future trips but I don't think it gives you your VWP rights back, it would be all upto the immigration officer at POE, if he would admit you or not.

Once you overstay you lose VWP privileges and will need a B.
