i am going to try banco galicia at las heras y ugarteche when i get there in october i hope they are agreeable. i miss not having a bank account. i own property and have a cdi.
I've heard CDI is one way of doing it but not if you're applying for residence as it conflicts with CUIL.
What worked for me is getting CUIL in local ANSES and opening an account in Santander with CUIL, precaria and passport.
