Never sign 10 month contracts. Insist on a 12 month contract with no summer pay. At least you can stay in country then and stay in your apartment. Otherwise what will you do with all your possessions for 2 months? Your new school/uni probably won't let you use their apartment for free for 2 months. And your current uni won't let an ex-worker use their apartment for free for 2 months.

If you have unpaid summer vacation and find a new job, I'm sure your uni will happily sign your release papers as it gets you out of their housing.
