Yes, we entered US through AVR program and no one asked about Self Quarrantine when we entered US, we were there for 5 days only and the CBP officer just checked for valid i-797 document and let us In.
Did anyone come back to US from Canada through AVR program recently. Did you follow the 14 day Self Quarantine also what questions did CBP Officer ask ?
Which terminal in YYZ did you enter through, also are there any temperature checks at airport , Also did they ask you any questions about Quarantine and show a proof of stay, i'm planning to stay at my sister's place so not sure what they will say
