Hello guys. I received my study permit on the 24th of May. On the POE/Letter of Introduction it says that my eTa was issued as part of my study permit application and that I do not need to apply for a new one. It also says the eTa number, the date it has been issued and the expiry date. When I log in my GcKey account I can see that the status of my eTa is valid. However, when I check the status of my eTa using the eTa status tool, it says 'no matches'. I have not applied for a new eTa. But if I apply for a new eTa, the eTa number will be different from the number shown on the Letter of Introduction. What should I do? Do I need to apply for a new eTa? I hope this does not cause any problems when I arrive at the airport.
