Are you saying the article I’ve linked, published by immigration attorneys, is wrong? They’ve quite clearly stated the opposite of your claims, that there is legal recourse available.
I don't see a disagreement about whether your article is correct. Your article talks about which crimes are deportable, not which crimes may result in a later visa application to the US being denied.
Exactly. Deportation proceedings are a separate issue from visa issuance and entry. Courts show far greater deference to the executive on visa issuance and entry decisions to non-residents (and temporary residents) than they do in deportation.
