The EU is a neolib capitalist hellhole. Leftists oppose it from an economic perspective. Libcucks liked to harp on the immigration stuff though, as though the EU is the only way you can have a free and just immigartion system. (Hint: it's not.)
The Schengen Area is a separate thing which does not require EU membership. It's more about free travel than immigration, but the EU isn't necessary for immigration, either.
