Yes, you can do it on your own but MAKE SURE you put ALL that you want - visits (when, how, who will pay), contact (phone, internet, when and how - will they have their own computers? What time of day and on what days?) VERY SPECIFICALLY in the agreement so that you have something that can be enforced. You can later informally agree to change what you have if it doesn't work, but if you have a vague order, then it's hard to enforce and it will be hard to get her back from overseas if she doesn't comply. Once she's gone you'll have a hard time making any changes if she stops being reasonable.
