Plus it is election time, Dems didnt want to be seen differently. Now it is over, it is a different scenario. Biden govt (I think) is not here to end this or take back, probably sth bureaucratically didnt work or was hard to make it happen. They would no-way NO WAY send all these people back home, trust me. You just have to have a strong mindset to deal with this pain. We are not talking about WWII era where half a million people would lose their status or have to return home.
