Can braces fix my underbite or do I need a jaw surgery? (photos)

I've been thinking of having braces but I was wondering if it could fix my underbite? I've had this since birth and I remembered I was bullied by my classmates when I was elementary because of this. And now I'm 23 I've become more conscious about my facial appearance because my lip isn't even. I'm not sure if my teeth causes this or I have problems in my jaw. I need your advice. Thank you
