Forget the company mandoob. they don't know crap! And often times, if you don't grease their palm with a lil extra cash, your transaction gets "lost." Do yourself a favor and go to the immigration office yourself and ask. Don't waste time asking people who have never had to deal with this. I have struggled to bring my family here and nothing has given me correct info like going to immigration office directly. it only takes about half hour of your day if you go early in the morning and they open as early as 7 am. your nationality, occupation, and salary have a lot to do with it along with your parents' age. go ask directly. they will not bite!
