Hi, I was on 3-yearTN visa (Canadian) until Dec 2018. In Nov 2018, my employer filed in-country I-129 for a 3-year extension to Dec, 20, 2021. However, no decision has been received after 3 years (case is in administrative processing). What are my options after Dec 20th? Would filing for another extension allow to remain in the country. Please advise. Thanks.
