I'll ask your forgiveness in advance. There's no clear answer for any given individual when they show up at the border of a third country from Afghanistan. The requirements seem to shift over time, depending on which mode of transportation they've used or whether they've crossed in accordance with local laws. As Ms. Kwan pointed out, many people seek to cross contrary to local laws in order to protect themselves. All of these factors impact how a country will respond to the different documents they have on hand.
With respect to certain travel documents that would permit a person to travel onward to Canada, we have made a decision that, before they get permission to travel to Canada, they need to be approved under the process and complete the process of getting here. We don't want to shortcut the process by issuing a travel document that gets a person to a third country but not on to Canada. We do want to make sure that, when a person gets that travel document, it's to come to Canada.
There are other things we're willing to do to work with people as they get partway through the process, such as completing their eligibility screening and getting their initial biographic details. We can provide information to that applicant about the status of their application. If they want to try to use it, they're free to, but we can't consistently say that a certain document entitles them to enter or exit a different country.
