Could you let me know why leave out Guelph? It looks pretty good from their website programs. Do they have a bad reputation with the immigration agencies?
One of the options we have is, for me to apply for a PhD program in Computer Science. I already have a masters with a 3+ GPA from a US University.
WIll this be a better option compared to MS for the wife?
Yes - that would be better most likely.
You seem determined to have your wife apply for a master's so I would go ahead and do it. You may get lucky. You should be looking to immigrate as professionals not student and I expect CIC will probably reach the same conclusion. No I would not recommend you apply to do a PhD program and then not attend.
Apologies for asking so many questions. Can you advice me on this scenario:
1) Both, wife and myself, apply for MS and PhD simultaneously. Both apply for student permits eventually.
2) Once we reach Canada, I give up doing PhD and she continues with MS - I stay back as spouse and work on open work permit.
Do you think this tactic may create issues? Kindly let me know your views either way.
I would like the CIC to know that our intention of entering Canada initially through the study permit is to immigrate - eventually as professionals that will add value to Canada, something that they are looking for.
If you make it clear you have no plans on returning to your home country and the main reason for the study permit is immigration, you'll significantly increase the chance of refusal. You need to demonstrate strong ties to your home country when you apply to show you plan to return home once your wife's studies are finished. While this may not make sense to you - that's how it is.
The rules favour younger people. I assume that you must be over 40 if you are not the primary applicant but your have the Master's degree not your wife.
If you have specialized IT skills you can always try to get hired and get an LMIA to get your Canadian job experience.
