My status expired on February 27, 2019. I applied for the online work permit extension on February 27,2019 at 9pm EST. I received a confirmation letter that is dated February 27, 2019 but in the letter it says that my application was received on February 28, 2019. I am so confused by this. My work permit receipt also says February 27, 2019. Do I need to restore my status? Do I have implied status?
