Students are encouraged to contact parents as soon as they have access to contact home to let them know they have arrived abroad safely. However, don't be surprised if you don't hear from your student within a couple of days. It can often be difficult to access email and phones immediately, plus students will be busy moving into housing, taking part in orientation, meeting new people, etc.
As far as communicating on a regular basis, be sure to talk with your student before they leave to come up with a plan and method of communication. Students can purchase international phone plans through their provider, they can purchase an inexpensive cell phone upon arrival, use email, or schedule Skype calls. You can also download free apps such as WhatsApp, which allows you to exchange messages using the internet. Make sure you take differences in time zones in consideration!
Be aware that communicating with your student every day while they are abroad may take away from their overall experience abroad and they may experience more extreme feelings of homesickness.
Advise your student to contact their Coggin Study Abroad Advisor if they have further questions regarding this.
