My Canadian Residence visa was approved a long time ago. I landed and stayed a week. I never received my residence card at the address given which remained valid even after I left. It may have gotten lost in the mail and was never received at the address I had given. I did not fulfill the residence requirements and my residence expired. I am now visiting Canada for a job interview. As a citizen of New Zealand I applied for an eTA but was asked to either renounce my residence or request an extension.
What would renouncing my residence consequences be?
Do I have any other choice?
