Hi, My H1B 6 year max out is by July end. My PERM was filed on April 2020, with no updates yet. My employer has initiated a Canadian visa for me (yet to approved). Does the 60 day grace period after H1B expiry apply for 6 year max out cases like me ? With current EO and restrictions on traveling back to US, will there be an issue if i overstay (without working) after my visa expiry till my Canadian visa is approved and travel to Canada from US ? Thanks
