need one more suggestion:
when i applied my surname and given names was wrong actually i put it wrongly, but they took it as correct form because whenever they issued me a letter or emailed me they wrote my surname and given names correctly. however on 26th february2014 they requested me to submit my passport, medical ,bank draft CAD 490 and police clrnce certificate, updated Schedule A /background declaration and i have submitted it by 19th March 2014. but last time when i updated Schedule A /background declaration i wrote my surname and given names correctly as shown in my passport ( almost inverse than before i,e my surname became given name and given name became surname). will there be any problem? need your expert opinion
