At 31 you should be alright getting an internship. Obtaining an internship is more about your interest in then field, willingness to go full time after graduation, and your ability to bring something to the table for the time you are there. If all those criteria are met, at 31 you still have another 20-25 years (easy) of possible work in you. Most programmers stick around for only a few years in any one company anyways.
