Leaving Canada while waiting for Canadian citizenship

[canadian.forever]

TLDR: wife moves to the US while waiting for Canadian citizenship, any consequences for the CAN citizenship process?

---

Hello People,

I'm Canadian, I've recently moved to the US on a work visa. My CAN PR wife will be joining me soon on a dependent visa (she cannot work in the US).

I'm planning to file a non-residency in Canada to avoid paying high taxes/taxes in both countries when I become a US resident in 183 days.

My wife has applied for CAN citizenship half a year ago, and we are not sure what the consequences are for the CAN citizenship process if she:

• moves to the US with me
• becomes a resident of the US in 183 days
• loses her Canadian residency address and other ties
• filing non-resident status in Canada, same as me (does she need to do it at all? can I do it without her doing it too?)

Question: Can it potentially affect her CAN citizenship application? She hasn't traveled much during the last 5 years.

I've researched a lot and cannot find a clear answer... Any help, including info on where to look for such help, would be appreciated.
We are noobs in all these legal things, unfortunately.

Thank you many times.
