I went through the process last week and I recall one of the recruiters said that there's no a specific time to wait to re-apply. You can do it whenever they're going again to your country, or if you want, you can go to any OD wherever in the world.
Did it take long for you to receive the offer of employment? And how long did they take to reply you once you sent them your medicals?
I've had my FI in Argentina and I'm waiting for the e-mail, a lil anxious haha. Greets!
