I am a canadian, working in US on a TN visa.
My present employer is not paying me on time and therefore I found another employer. I have my TN visa valid for 7 more months. How difficult is it going to be at the border, to get the visa. I was initially denied the TN visa 2 times before giving it to me in my third attempt. Also I don't want to tell my present employer untill I get the TN visa on the new employer. My employer did not issue me a paycheck yet. Moreover, my employer who was on TN visa itself did not get his TN extension. Will that affect me badly?
Is this going to affect me at the border? Can I send my application to change my employer by mail?
