After the appeal is successful, the reunited immigrants in Canada need to have a physical examination and send their passports. How long does it take to get a visa? Is there a problem if there is no signature on the passport? After the successful appeal of Canada's reunited immigrants, they need to have a medical examination and send their passports, and usually they can get a visa in about one month. However, the specific time may change due to the applicant's personal situation and different handling procedures.

Regarding the problem of not signing the passport, if the passport is not signed, it may cause some problems. In Canada, a passport is an important document to confirm your identity, and you need to show your passport when you enter the country. If your passport is unsigned, it may be considered invalid, which may lead to your inability to enter Canada. Therefore, if you find that your passport is unsigned, you should contact the Canadian embassy or consulate in your area as soon as possible to ask them how to deal with this situation and take remedial measures as soon as possible.

Generally speaking, if you want to ensure the smooth progress of your immigration application and avoid problems caused by your passport not being signed, I suggest you be patient and cautious in the application process, communicate with relevant institutions in time and consult professionals.
