Trying to do A-Levels abroad.

I'm 17, I completed my GCSE's and now I wish to do A-levels. I did my GCSE's a year late due to a different circumstance. My issue is that I want to do A-Levels, but both of my parents want to go back to their country. I can't stay in the UK alone, and I also can't go to a school there for IA-Levels (the city I live in doesn't have such schools). So, now I'm stuck on what to do. I don't know if online school is worth the money, and I don't know if there are sixth form colleges that accept students who study abroad yet still attend when they can. Any help?

In there a reason you specifically want to do A levels / International A levels? Could you not take whatever the usual qualification is in the country you are moving to, and apply to university (if that's you're ultimate goal) using those qualifications instead?

A levels are a level 3 qualification to prepare you for your next steps. Your parent’s country also has their own level 3 qualifications.
Which country are they going to?

To be honest, it's only because I got used to the system in the UK that I don't know how it could work elsewhere. English is my first language, and if I go back to Iraq it would be really hard to get used to the language. I also don't want to go to university in Iraq, or at least I don't think I want to right now. I like the idea of studying abroad, but I fear for my future and don't know what to decide.
