Hello everyone, as this is my first post let me introduce myself quickly. I’m a French 28yo male, working as an English teacher around the globe. I’ve been in Madrid for a week in July and met my girlfriend there. She’s venezolan, 21, been in Spain for 2 years and lives with her mother, which herself has been in Spain for more than 10years, she told me.
My problem is the following. She (my girlfriend) is currently working as an escort. It didn’t bother me at first as I thought she enjoyed it, and if she’d be happy doing that, I’d be happy for her. But lately she actually told me that she hates the job, for obvious reasons, and she’s doing it because she doesn’t have papers, and it’s the only way for her to get some (work as an escort for a few years and get papers).
Now, she doesn’t speaks English, I don’t speak much Spanish so communication is bit tough between us and I have trouble understanding exactly her situation. What strikes me is that she’s young, gorgeous, smart, and have extended knowledge of anatomy and fitness, so any gym or bar or club could give her a job. I’m not familiar with the system in Spain and it’s killing me to watch her endure this.
Is it possible for someone without qualifications in her situation to find a normal job and get papers? What about a student visa? I could support her financially if this would be an option…  She wants a residence permit to stay in Spain with her mom. Isn’t there any bloodline related permit she could benefit from?

Thanks for reading this, any advice will be highly appreciated.
