How can I become my parents caregiver?

If you are referring to being paid to provide their care, here is information from this forum's home page:

Based on your profile, it sounds like you already are the caregiver for your parents: unpaid family member that is expected to do everything and fulfill all needs of parents. (I wanted to say something funny and witty here, but I’m exhausted tonight, so my brain isn’t cooperating!)

Can you explain what you mean?
