I am a permanent resident in Canada and I have not yet applied for citizenship. I am trying to get a visa to go with my team to St. Louis and I have a few questions.
I am applying through the us visa website:
https://ais.usvisa-info.com/en-ca/niv/. I don't know which category the visa would be in. There are a few, but none seem to match up. I have a letter from the school explaining why I am going to the US. Is that sufficient? I am also wondering how long the process would take. I am applying at the US Visa Consolate in Toronto. Any other tips would be great.
If anyone who has gone through this before could please help, I would really appreciate it.
