Hello everyone and thanks for helpfull comments and sulotions

I am an Afghan national, and have been working for.DOS about 3 years, i have passed my first poly test, but fail second after 2 years due to the shift duty and not being ready,
Actually being fail with poly-test is a big loss out here, cant find job in any U.S agancy where i have good working experience and a written proof of valuable services which i offered during my duty,
To be honest, i am not alier nor a criminal, have a very clear background in Afghanistan Gov and the long while i was working for DOS here in Afghanistan.
Can i apeal for my 2nd poly-test? and How?

your kind answers are highly appreciated in advance
