Well, the first matter for consideration will be your age.... You may have read this already, but very few MBA programs are gonna see candidates who are 35. There are first of all issues with fit with the rest of the class whose average age will be about 25.... and secondly, they might wonder "Why have you not done this already". This is all the moreso true for US programs, and for Top programs.
Once you get out of the US and out of the top 15, things become a lot more flexible, and you see people who are a bit older getting in. But you do have to have a logical and clear narrative as to a) why you are doing this NOW b) connect your past experience to your future goals c) show that you are in fact capable of succeeding in this.
Hope this helps,
