[Edit: removed stuff about the Schengen area]

Jobs aside, I've loved the last two years I've spent here in Ireland. The people are lovely, as is the country itself. Still on the expensive side, but we're having price corrections along with the recession. :-)

Edit: I couldn't reply so Ill explain here. OPT is Optional Practical Training, it is what F1 visa holders(full time students) can do. We are able to stay for 29 months after graduation, to work in the field we studied for in order to get practical training.

EDIT: Section 7.2.1 specifically.

Careful there. It's almost certainly not. Unless you're just a "brain" doing meetings only, you'd almost certainly be doing something that could be considered "work" and it doesn't matter if you're not being paid.

From my understanding you could do it, because foreigners are allowed to own or start U.S. corporations. I'm not sure how much work on the project you would have to do at home versus here, though.
