1. how to get police certificate in China and USA? what is the simple usual way to get it?
*** 中國的應該是到你檔案所在的城市的公證處辦. 美國的應該是等到canada 通知你時再辦( 但我不了解具體辦理程序)
3.finish two master degrees in USA, do i still need to take any language test to show I can get full score in English?
*** Usually a person who has USA degree and USA work experience can get test waived. But it will be a big plus if you give a good statement about your English skill.
