I'm not sure that I can speak to whether corruption is there or not, but I know that it is a really difficult process, not just for Venezuelans but for other migrants. It has been an issue that has come up a lot in the past for economic migrants as well.
I think there are a lot of barriers that stand in the way. One positive example recently has been Peru. Before the constitutional crisis that's going on, there was an initiative from the government to allow Venezuelans with medical backgrounds to work during the pandemic as doctors, to enter the medical system to support the medical system. That arrangement would be in place moving forward, so clearly there are things that governments can do to expedite this process.
Then, on the flip side, in Colombia the government tried to do the exact same thing, but it met a lot of political backlash from the medical community. You can see that there's a lot of political push-back, not just from the government but from powerful interests.
There are definitely some serious barriers that are in the way, and perhaps corruption also has something to do with it. I can't speak to that.
