What's with the migration?

Moving files means that you have applied for a visa in Canada before, and whether the visa is approved or not, you have left a record in Canada. If you want to apply for immigration to Canada, you need to transfer from Canada to caips, which is called document transfer. After the transfer, you need to check whether there is any contradiction between the information you filled in when applying for a visa and the information you need to fill in when you immigrate.
