@254:
there are places that require a rating on the aeroplane you'll be piloting before you can get a work visa, and since the FAA system doesn't do ratings, it can be difficult, again depending upon the current political climate, to get approved for a work visa because you don't have a document that says you're qualified to fly a Cessna 172, even if you do have 125 hours on them.
Now, many places have been going through this for some time, and have worked out agreements with the authorities, so you might be able to fly a Cessna 206 without any hours on one in some places, but in others you will need an instructors signature in your logbook or even a separate document stating that you're qualified to fly said aeroplane and have put in X number of hours under their supervision.
But next week, that might not be enough.
You will need to contact the governing body in the country you will be flying to know what they want this week. Next week, you will need to ask again.
Hiring companies for the last several years have been guessing what their government will accept and what they won't accept, sometimes successfully, and sometimes not so successfully.
(most "type ratings" outside the FAA for specific planes require a number of hours, generally 5, before you can be type rated, so a "checkout" at the local FBO for a Cessna 206 isn't the same as a type rating as far as they are concerned, but if you've been checked out and have flown 10 hours in one, you're likely - today, in some countries - to be accepted as "type rated" on the C206, but don't quote me, because that was last week, and it really does change week to week in some places)
Your chances of being hired if you don't go to most of these countries is absolutely nil (zero for americans). About 1 in 5 if you go for a month or more, 1 in 3 if you stay for 6 months and aren't an idiot or a jerk.
I know that some years the odds are better and some years the odds are worse, but most will tell you that there were X hired out of Y pilots that year, and when you work it out, it's 1 in 5 or so.
