though they do put B1/B2 in the same catagery. What she cares is I have a company letter showing I am going there for attending a trade show (you won't believe there are thousands of trade shows in US every year) & the company take care of the expense for me. I gave them the reason why I have to go & they know I have my family (2 sons) in Canada & a job which have quite strong ties here, then she gave it to me.
For my understanding, what they really want to know is whether you have strong ties in Canada (like family, a decent job, a house ) & enough money which means you won't stay in the US & won't come back..
