Hello everyone, Just had my citizenship Oath ceremony today. I'm going to apply for my Canadian passport next Tuesday. I was an Indian citizen and had a B1/B2 visa. I know I can use that to attend the conference. Since I'm a new Canadian citizen I want to make sure I don't screw up on my very first trip with the new passport. Do I even need a US visa for the conference, I know I don't need a US visa for vacation/non-business travels. Is that considered business? If a Visa is required can I just ask them to transfer the visa to the new citizenship on the port of entry? or do I have to go through the entire process to get the Visa, the conference is on April 3rd and April 4th. Thanks for your help in advance.
