Biden would look at El Salvador and Honduras but not much for Nepal , it won't be his priority. But like I said Trump has successfully built the wall (paper wall) to prevent most new legal and impossible for illegals to reside in this country. So even If Biden win, it will be hard from him to undo most of the Trump immigration Executive Orders and rules. There will be litigation from anti-immigrant group such as FAIR and others if he try to undo some of the rulings, Just like ACLU and AILA is doing now. So its all politics, and immigrants are the football, keep getting kicked around.
