It depends entirely on the person, their history, where they're from, etc. If your PA was in the military or police, expect it to take a while. If they haven't lived in other countries, haven't worked for the government, are young, and have a clean record, then it can often be pretty quick.I am may applicant and I passed the eligibility how long does it take my security screening?
You're making progress, so just stay patient and you'll be done soon!
