I have had braces on for a year and a month. Is it possible to get my top braces off before my bottom?

Hello, Thanks for your question. In very rare situations either top or bottom braces are removed prior to the opposite. That is because the specialist needs to make sure that the bite fits good and for that purpose elastics /rubber bands are used.  So most likely that is not going to happen.Thanks

Without photographs I am limited in my ability to answer your question. Your best option is to ask this question to the dentist doing your orthodontics.
