I’m not a lawyer, but from what I understand is the fed courts have very limited authority with the new travel ban, since Trump just ordered the embassies to stop issuing visas, and the courts have no say in embassy orders.
The people at issue are on foreign soil, not stopped at our airports. The one judge issued a ‘stay’ for a specific family but the question remains whether those family members actually have all the needed documents. Given that, how can a judge force the executive branch to issue those documents to foreigners on foreign soil.
