looks like my last name is too ethnic...despite the official laws about passports not being official yet, they are starting to ask...and if you don't have one...get ready for questions. In the end my family was all set but were told "next time, we want to see passports"...just FYI since there are people who tend to ask this question.
I've said it before and it's subjective really..depends on who you get and they judge you on appearance etc.
