So if I use an official taxi I can likely bypass long waits? I wouldn’t mind paying extra to bypass the queues as time is arguably the most valuable commodity on such a short trip.I spend a month or two at a time in the area for years now, it didn't used to be like that but that's how it is now. There's not always a large line, but more often than not there is. Most of the time, if you're in an official taxi it won't apply to you, but IMO unless you really need something in Brazil I wouldn't risk crossing. Most land borders with Paraguay, Brazil & a few Bolivian ones are like this now. Do not expect quick crossings.

Largas colas para entrar a Iguazú por el éxodo brasileño | El Territorio
Hubo unos tres kilómetros de autos esperando cruzar, la misma distancia entre la Aduana argentina y brasileña. Pese al refuerzo de personal, existió demoras en Migracioneswww.elterritorio.com.ar
Just a tip for those doing tourism in the area, that entire Parana River area is filled with gorgeous waterfalls, probably dozens - Iguazu just happens to be the most touristy. If you rent a car in Foz or CDE, then drive up to Guaira, I think that waterfall is actually bigger in terms of volume than Iguazu & there's 0 tourists (there's not much accommodation options either). Iguazu area is gorgeous but suffers from mass tourism.
I am sure renting a car would be a great way to see it better but I haven’t driven in too long to be comfortable driving here. I’ve never even driven a left hand drive haha
