stealth, exactly!
.. Rudith, you are right..Not only nationality, but Gender as well.. ALL what a QUOTA contains.. that's how Government Quota works. You are new here, but you got it right.. honestly, I never come accross a quota like "Lybian - General Manager - Female".. That would be unrealistic.
Usually:
" Manager - USA - Male"
" Consultant - canadian - Male"
" Technician - Filipino - male"
" Administrative - Filipina - Female".
...so when some nigerian fellow complains about the Company being "racist" by not hiring him.. Hey, Nigerian dude, the Company simply has no quota for you!
