I'm also curious to hear others' thoughts on this, as I am in almost an identical situation. I'm suppose to be heading down to Latin America from the states for my first international job. Like you, I've been told by my current district (whom I really enjoy working for) that they will hold off hiring my position for another week and half at this point, if I want to stay. In addition to your concerns, my background check to get my visa has been held up and they've told me they have no idea when that process will be able to move forward and how long it will take once it does.

At this point I think I am leaning towards saying; however, I also need to figure out what to do with my contract. I was hired directly through the school.
