Hi there, it appears that you first need to get clarity if MBA will truly help you get where you want to go. Moving from a tech to managerial role is often a good reason, but if you want to stay within the same company, see if you can get promoted through lateral hire?
MBA is a big investment of time and money, esp. the full-time programs. Unless you really want to switch careers, geographies, a full-time program might not be the best value for you.
One good way to start would be to talk to people who are in the roles you aspire for. Ask them how they reached there and if MBA will really help you. Once you are sure you want to do an MBA, then start looking at what schools would be good fit for you.
EU schools are more open to older applicants, but also consider the added factors related to lost wages, work authorization, relocation etc.
Good luck!
