Dubai Here I Come?

I applied for a job in Dubai somewhere last month and received an email from the HR two weeks ago asking for my current and expected salary. Seems I've been shortlisted for an interview. Well, the offer is very attractive (perk wise, I don't know how much basic salary I get to bring home every month) and loking forward to the interview, hopefully soon. I haven't decided whether I'd really go or not, if offered but I'm keeping my mind open if there is really a job offer coming from them. Perhaps it's time to start anew, many issues to think through though, particularly my health. I'm sure life would be interesting in a new environment.
