Guys, I guess Gauri;s Third Point is very critical.
Seniors Please share you opinion specially in reference to her third Point which is
3. CAN ANYONE'S ANNONYMOUS EMAIL AGAINST US , AFFECT OUR CASE??
Annonymous complaint can be entertained by the Visa Office or CIC if the details are correct and the allegations are serious in nature. It can affect the application process also.
Regarding name change, i would advise dont go for name change now. We should avoid cofusion and keep the matter simple. In your application you have already mentioned your name and their is column for previous name also. You could have changed the maiden name before filing the application, it would have been better at that time. Old address on PP is not important , only thing is that you would get PCC of that address. You can change the address on your passport and even get new booklet issued. Updating your resume is also not important. But updating on new job or place of stay etc is important to inform.
How can it be possible that your consultant had send your affidavit and it is not signed??. In fact affidavit is not required for showing job responsibilities, it is the employer who states job responsibilities on his letter head and it does not bear employees signatures.
You can send IT returns,can update the Visa Office regarding your new qualification etc, can write a cover letter for it.
