I'm a H1-B holder. I got my I140 and I485 case number last month. This month I traveled to Canada for one week(just for fun and didn't do visa application in USA embassy). When I reentered the USA the officer issued me a new I94 with the same expiration day as my old I94. He returned the old I94(which is the lower portion of my H1-B approve notice) back to me. Since the new I94 has different number I'm wondering whether this will affect my I140 and I485 application. Thank you for any info!
