You live in tajikistan? Actually applicants from tajistkan are super lucky their process is moving fast. Unfortunately from pakistan it takes more time fro flights after medical etc
Looks like special program applicants are prioritized thats why process is running super slow. Exit interview is really hard to guess, cant say what were the reason
Did they undergo police check after exit interview? Is police check still required if ecit interview is done?
are they private sponsored? their flight chartered ones?
I think its not this simple, exit permit is issued by one of ministry , the ministry send police at ur address for investigation etc. then police sends back to minsitry, it takes like 1 month. Its what i heard from ppl who had done
