Thanks. Yes, I took an appointment at this (Pembina) EC.I only made single appointment at Whirlpool Bridge, at Niagara Falls, NY
At this centre both CBP and CBSA officers were there
Choose the centre and quite likely at the centre both officers will be available
Just one more question, just carrying the passport is enough or should carry any other documents? I don't see anything mentioned in this regard on the website. Thanks.
