Our appointment was for 11am, but they said to arrive 15 minutes early. You will get a green laminated card with a number on it. They will call your colour and number. The entire interview itself was only 10-15 min, but we had to wait behind other landing interviews. We were there for just over an hour total.
She asked me (the sponsor) if I have ever declared bankruptcy and if I am willing to sponsor him for 3 years. She asked my hubby (PA) if he had any criminal record/convictions, any other marriages/relationships, or any children he did not declare during the process.
Then she stamped his COPR and sent us on our way. Very easy overall.
