回複：我是否可以到圖書館工作呢?

it depends whether this position need any account acknowledge, or why they will hire your ? My wife got MS in Computer Science, and find technician Job in biology lab, the only thing related with CS is that they have database need a little computer acknowledge. Actually when she submit OPT, none one even both as what's her Major. Now we have green card.

The only trick is, do you need your employer to sponsor your H1 after OPT expire, if yes, then it will be trouble to get H1 if this position have nothing or little with account
