Is it possible to work in "country X" with a FAA pilot licence...?
Frequent question.

The way newly qualified pilots should do, after getting any licence (i.e. FAA or JAR) should be to answer pilot job openings on the net, the licence required is almost always specified, as well as the qualifications, such as "FAA CPL/IR/ME" with minimum 1,000 hrs total time, 500 hrs PIC multiengine.

Majority of pilot applicants send their C.V. with or without knowing if their licence is approved for a job in that country, anyway. Sending a C.V. does not cost much except your time and effort. If you get an answer, they might, or might not tell you that you do, or do not meet their requirements.

If they want you (or need you) they will hire you. A current passport will always be required. Sending a job application to an aviation company FIRST, before holding a licence, then deciding to do that FAA (or JAR) licence, is the wrong order of things. If they write "yes we accept FAA licences", may mean that they openings now. These openings might no longer exist a year later, when completing your training.
