Some important departments to contact include:
Housing: If you live on campus, let the housing office know when you will be studying abroad and if you wish to request housing for when you return.
Student Employment: If you currently have a student employment position, inform your supervisor of your plans to study abroad once you've been accepted to the program. Important information to share with them is your last day before going abroad as well as the date you are able to return to work once you return.
International Student Services: If you are an international student, contact the International Student Services team, especially if you are close to graduating and considering Optional Practical Training (OPT) or other post-completion options.
Disability Services: Let your Disability Services Counselor know that you will study abroad so they can ensure you'll have access to everything you'll need there.
Personal Counseling: Let your counselor know that you will study abroad. They can provide useful tips and help you set up counseling services in Valencia.
