The literal meaning of this phrase is easy, but in which contexts is it used? Does it have any figurative meaning?
You know, I am not a native speaker, and so far a couple of people have used this phrase when they replied to me.
One incident was on FB. I had posted something, and an Americanized friend commented: "Welcome abroad". I had a bad feeling about his comment, because it seemed to me that he was kinda humiliating my post as somebody who was new in the States! I'm not sure though.
The second incident, was an email reply from a professor, from whom I had asked to do TA for her course. She wrote back to me: "your background is excellent to do TA for this course. Welcome abroad"
Could you please ellaborate?
