My parents did medical exam in June 2011. I sent an email to embassy in August to ask the status of the case and how to get their passport back if they need to travel. They replied right away and told me that they are still waiting for the landing fee payment confirmation from the Mississauga center. They told me that my parents can borrow passports from them, but have to return them back once they come back China. I was a little upset since i am 100% sure that i paid landing fee for them in 2006 when i applied sponship for them, but i went to the bank to pay the landing fee again right away. I emailed the payment receipt to them in late August. My parents called me yesterday and told me that they got the landing paper. I believe that if you dont mind to pay double landing fee, your parents case will be processed faster :)
