You might be sitting for months in training, depending on what country hires you. I know a few guys who worked in other countries. It has been a while, but some TWA 747 pilots who retired a few years early reportedly sat for about six months in ground school class in Japan, as if they knew nothing about trans-oceanic operations, or even basic aviation.
Be aware that some countries, even outside of Europe, require a huge amount of academic trivia to be learned, much of which has little connection or applicability to flight operations' situational awareness nor decision-making. But maybe this has improved with so many openings in Asia for foreign pilots.
As a pilot in the US, you might encounter a bit of silence on the matter of helping you pursue jobs in other countries, based upon the common impression (or reality) that not many foreign guys are hired by airlines here, or allowed to work here. And for what it is worth, a former US major airline Chief Pilot was reportedly in charge of hiring recently at Emirates, in Dubai. The US pilots hired there recently might not have already had a given type rating.
Overs the years of reading Pprune, it has been stated often that some contract firms are good at complying with a contract for you to work 2-4 years with a carrier. Others have been accused of keeping, contrary to the contract, a chunk of your first year pay etc, with little recourse for the pilot, unless one flies to a very remote island chain and goes to court. Good luck.
