If she is just coming for a visit then she has to apply for a Temporary Resident Visa.

The most important aspect of this application will be for her to show strong ties to back home.

Canada Immigration will worry that she is not planning to leave after the visit because she is married to you.

Here is a link to the information you will need:

http://www.cic.gc.ca/english/information/applications/visa.asp

So she applies for the visa.

You can see all the information at the link I provided.

And she has to say why she is coming and show what she has to go back for.

So if she has a job, a house, family, assets back home that would work.

But if she cannot prove this they won't give her the visa.

She cannot enter with the intention of remaining and the concern is always that visitors don't plan on leaving and over-stay illegally.

She has to show strong ties to back home and when she arrives at the border must have a round trip ticket.

Sometimes you may be asked to send a letter of invitation.

If he has been living there that will help for sure.

It does not sound like this will be hard in her case.

No

Nothing can affect his citizenship in Canada.

And your son living there makes her situation very much simpler.

There should not be a question of her wanting to stay in Canada when her family and spouse are there.

I provided you with a link to the webpage that has all the information including the forms.

Just go to the link I provided and then follow the instructions there.

It is not that hard once you take the time to read the pages.

It looks overwhelming but it will not be.

Yes he can come too.

They live there and he is bringing her to visit family here.

It is very straightforward.

I don't think you are seeing the full screen when you are reading my answers.

Sometimes you have to scroll up to the top.

I tend to type a lot and I think that could be why you are missing parts of my answer.

Why not scroll up to the top now and read the full chat and then let me know if you are missing anything.

great

Why not keep my name in case you need me again.\

If you post on this site again you can put my name into the subject line next time.

That way I will be sure to answer.

Great

Please rate me before you go.

The way the site works is that even though you paid the site I do not get paid unless you rate me postitively.

Thanks!
