How did you have this offer?

In this question the Visa Officer is asking about how you get your H1B job.

Possible Answer:

• I uploaded my resume in #WEB SITE NAME# and they called me over the phone and check my availability. Then they interviewed me and after the interview they send me the offer letter.
• I am searching for a good opportunity to work in USA and I find their site through #SEARCH ENGINE NAME# search and applied through their website. After a week they called me over the phone and check my availability. Then they interviewed me and after the interview they send me the offer letter.
• I have a friend in #EMPLOYER CITY NAME# who know about this company and give their website address. Then I send my resume to their email address and they interviewed me and after the interview they send me the offer letter.

If you are already in USA in some other visa (L1B or B1) then don’t tell that you looking for an opportunity in USA instead tell the VO officer that you are looking for good opportunity.
