You just need a new visitor visa if you want to return before your permit expires. But you should have a plan of what you will do when the permit expires, as CBSA will ask you.

So the visa is a travel document, which means that it is proof your daughter can travel to Canada until March 2019. If her passport wasn’t going to expire, it’s entirely possible she could be admitted longer than through March 2019.

However, because her passport will expire, it’s very likely she will be admitted until the date of her passport expiry. So yes, she should apply for a new passport. She doesn’t have to apply for a new TRV as long as you enter Canada before March.

If it’s just a normal visitor visa application, then both of you can write and sign the invitation letter.

If this is a Super Visa application it’s more complicated because your husban inviting his in-laws might not be considered legitimate. But you are not eligible until you have PR.

You either have to use the name on your identitty documents for the application or you have to do what’s necessary to change your name on those documents before you apply.

This actually doesn’t matter.

That’s because your visa is a “travel document”, giving you permission to travel to Canada where the border guard will decide whether or not you could enter.

Your work permit is your “status document” which gives you permission to work in Canada.

As long as you are not travelling outside of Canada during your work permit’s validity, you do not need to renew your visa.

Now, if you do want to travel, you need to apply for that visa extension and you should be able to do so online at IRCC’s website.

If you are married your husband can apply for an open work permit to accompany you on your work permit. If you are not married he cannot do that.

You’re past the eligiblity window for an open work permit. If you can get a job offer from a Canadian employer, you can still apply for a work permit. But you need to have status or you need to leave.

The short answer is “no”. You cannot go from a study permit to PR. That is impossible.

If your fiance is Canadian (citizen or PR) they can sponsor you for permanent residence.

If your study permit expired less than 90 days ago, you can apply for an “open” work permit. If you work in Canada in a skilled occupation for at least a year you should be eligible to apply for PR then.

There are no special visas for this situation. Anyone who does not have status in Canada needs to apply for a temprorary resident visa (i.e. a “visitor visa”).

No.

If your multiple entry visa is still valid, you can still use it. A temporary resident visa and a work permit are for two different things: travel to Canada and work in Canada.
