Since you ask, yes, I have gone through Brit Millah. Incidentally, did you know that, during partition, Muslims in Pakistan were fishing out Hindus by raiding villages and asking men to drop their pants/dhotis and checking to see if they were circumcised? If so, the pass, if not, then instant beheading.The Pakistani Jews managed to get away with it coz they were also circumcised and were thus mistaken for Muslims by the Muslims.Thus, they managed to make it to India across the border. Some Pakistani Jews even took Hindu children with them to India (posing them as their own children) who were orphaned in the violence.
Also, the noun "Jew" is regarded as offensive when used by a gentile. This is so because traditionally it was used as an antisemitic pejorative ("You dirty Jew","You money-grubbing Jew","Die Jew-scum" etc.). The adjective "Jewish" is better. Just FYI. 
Regarding passports, did you know that Pakistani passports force their citizens to officially acknowledge Mohamed as the one true prophet, even if you are a Hindu, Christian or Sikh Pakistani?
