I applied a J-1 visa in 2013 as an exchange student to a US university. Unfortunately, the US embassy issued my visa too late so I decided not to come to US at that moment. In other words, I did not use that J-1 visa at all.
One year later, I came to US as a F-1 student. I will graduate soon and start my new job in a few months. I would like to apply for H1B visa and the company is willing to sponsor it.
In this case, do I need to apply for the J-1 waiver of the two-year home-country physical presence requirement from USCIS and my home country? It seems my case is a "corner case" because the DS3035 (the form for the waiver) form requires an entry date of the J-1 visa. Obviously I do not have those information because my J-1 visa is never used.
Edit: Sorry about posting this thread on this site. I thought that the "travel" site allowed any types of posts about visa questions. I should have read the guidelines before posting it. Is it possible to transfer this post to the expatriates site?
The reason I want to transfer this post is that Michael's answer is quite good and solves my "corner-case" problem. It might be useful for some people in the same situation.
