Talk to Dermatologist on Braces Treatment

I came to you at the start of this month you explain really well about all questions. I have few more arise in my mind 1) You told me my treatment plan will be for 2 years but i have to move abroad next year what is the possible solution? 2) What is the payment plan i.e its fully advance or in installments 3) I have little spaces in my teeths so as you told that i have to extract 2 upper teeths for better results my question is can we make spaces by "IPR" method?
