We are landed immigrants from US. We moved to Canada about 7 months back. Our daughter is a US citizen. She was born after we our Permanent Residency was approved.
We have applied for our daughter's Permanent Residency immediately after we moved here. Her application is in process in Buuffalo.
Will it be a problem for our daugher to stay here on her US passport while her application is in process in Buffalo?
US citizens do not require a formal visa. Generally speaking, a US citizen can enter canada with a passport that serves as a visitor visa for 6 months at a time. Sometimes longer. Check with CIC.
You need a visa for your daughter before applying for her. otherwise entry might be restricted i.e. at a certain point one will have to stay out of country with the baby while sponsorship is in process as the 6 months visa might not be extended . i think not quite sure.
