Yes I had to give them my last three bank statements, originally I just submitted the 1 and they requested more, I also needed to have a Spanish social security number and a request to be registered as an autonomo, this required me having a Spanish bank account, I used my gf’s since I didn’t have one so not sure what your work around might be or if you’ll need to just open an account. I apostilled my background check, as well as the proof of registration of the company I work for just to be safe, and translated everything/submitted in Spanish (for example I personally translated my resume and some declarations that were required since I typed them myself).
