I have I-140 approved 9 years ago - can I use that for h1b extension with new employer now. I am currently in Canada and just became a Canadian citizen and trying to get back to the USA. Is it possible to use that i-140 approved copy and file h1b extn thro new employer in the USA. since I heard that we can’t use it if you have stayed outside the USA for more than a year for h1b extension with the new employer. you can use it within a year only for h1b extension. so, we need to apply for new h1b thro lottery.kindly provide your valuable feedback.
