Mmmm - I was going to ask something similar on here. A member of my family works for a fairly large company and does the hiring for that part of the country. For security reasons, as above, Passports or FULL Birth Certificates are requested. On one occasion, as the potential employee had no passport, he had to apply for a copy of a full Birth Certificate. Anyway, to cut a long story short, it turns out this guy found out something that he'd never previously known which could have ruined his life! My family member was devastated that they'd put this person in such a position and wants to know 'surely, there must be something else the government can come up with to ensure people are working legally?' Incidentally, this guy only had a week in which to accept the job!
