The decision of ICE essentially was to not change anything. A student on F1 is only permitted to take certain number of online classes and must maintain his status with in person classes. The change to online classes means this affects ones status and the ICE notice meant they will not make any changes to these rules even in this situation. What people are saying is that this affects ones work status if he leaves the US post study but ideally a student is a student not seeking work or immigration into the US especially given that the H1B is suspended and OPT is not work it’s training. If the university says class is online then it means there is no reason for a student to live in the US. People confuse students with long term immigration even if that maybe the intention of the student. They are just students who are paying tuition and living in the US as far as anyone is concerned.
