Why are you guys pushing need to invade country? It's way too vast, it's far better to keep near the coast, occupying and running those major USA cities for your own goals is enough of the trouble. Also in Europe we had a lot of enthusiastic people. Like in Lithuania, it was very popular to join resistance fighting, but you know that? It shrunk many times within a year then realities of hiding in the forest struck. And that's on top of having to suffer insufferable USSR regime.
You do not need to expand in depth. Just raid USA if needed, coasts are all you need to hold and in depth defense perimeter will create killing fields for any USA's army operations. Then establish puppet regime in those coast cities. New regime, with your military backing and backing of its most luxurious cities will survive against cheer mass of the rest of USA. Manipulate them into fighting wars among themselves, try to divide USA since this is the goal. While USA is united, it's unassailable. While divided it's weak.
