Experience letters from previous employers


New Member

I am not sure whether this is the right forum for my question. I am thinking of applying for green card. Right now I am on TN visa. I have been working in my current job for 4.5 years on TN. I read in this web site that I cant use the 4.5 years experience when apply for GC. I left USA in 2001 to Canada and came back in 2012 to USA. While I was in Canada I was self employed. Now to apply for GC how long back I need to submit employment letters from previous employers. I had breaks in between assignment in canada. I am not sure how long back history needs to submit for GC. Please help
