i applied to sponsor my spouse here in canada. We sent an application for an open work permit to the same location afterwards which was accepted. I received a confirmation of my application today via mail with Application number and UCI number. Yesterday my wife received a seperate mail with same application number but different uci number. She has been asked to link her paper application online. We tried linking yesterday with details in application and when that did not go through we used the uci/application number but got logged out after 5 tries. Today we attempted using the permanent resident application and subsequently the trv under work permit but we are still unable to link the application. We have complained under technical difficulties but no response yet. Pls what is the proper procedure to link the application and what application are we supposed to be linking?
