- get your paperwork in ASAP! There might be delays if you require an embassy interview in Toronto!
- also if there are no dates available for the embassy interview, you should request for an EXPEDITED interview!
- You can't bring your phones into the embassy, but there is a convenient store down the street where you can store your stuff!
