And clarify the citizenship of who exactly are American citizens. For instance, Israelites are not Americans, Africans are not Americans, non Whites can not ever be American, etc. "Send them back..." I'd opt for a voluntary repatriation to their original continent/country of their choosing, all fairs paid, one way only. With a time limit, something like 90 days. With all constraints removed on punishment for White Americans "helping them self deport" completely removed. It would be a logistics nightmare, but it's doable. White men can accomplish absolutely anything when they put their minds and technology to test.
