Most countries will only issue a work permit or relevant visa to a foreigner if there is a sponsoring employer who can prove to that countries immigration department that there is a real need for having to import your talent, skill or labour. This usually happens when there is a demonstrated need or shortage from within a countries own indigenous workforce.
There are many countries that issue work permits to foreign pilots in recognition of a shortage within their own population base. Usually the shortage arises at the higher skill or experience levels. Rarely is there any shortage of trainee or apprentice level positions.
There can sometimes be a general freedom of labour between member states of various political unions (for example the EU,) although in practice the reality is often more constrained by language or treaty issues.
There is no shortage of pilots (at any level) within the USA. Unless you had a conferred right of entry, and right to work by virtue of something more fundamental, your chances of being granted a green card even if you could find a sponsoring employer, are so small as to be virtually non-existent. The same holds true for many other countries.
Outside of the EU (and accepting the difficulties already referred to,) you would have to find an employer who could convince their own immigration authority that there was a case for issuing you with a work permit. Outside of the very limited dispensations that a few countries allow, (for example students and young people to undertake limited types of work,) most countries wouldn't entertain the idea of a work permit for somebody who didn't have both a sponsoring employer and a skill for which there was a declared need.
i really wouldn't think that the embassy would say you cant get a work permit because you hold this passport unless they had some reason example you have a criminal background or political issues
Oh yes they would! The passport would confer no right to work at all unless the country had both a requirement,
and the applicant had a sponsor.
