First and foremost, if you are considering volunteering overseas I commend you. It takes a certain type of person to want to spend their time abroad helping people, and Projects Abroad will help you immensely throughout the entire process as they did for me.
I was in Peru for a month doing Archaeology, though I got to meet other volunteers doing teaching, care, and other projects. Everyone was happy in their placement and enjoyed being apart of the local Peruvian lifestyle. Living with a local host family when I knew no Spanish was extremely daunting at first but I had no issues being able to communicate everything I needed with them, especially with my supervisor readily willing to help translate if I needed it. Mostly a series of hand gestures was enough, and they were able to teach me quite a bit!
The placement itself was incredibly fun and time went by extremely quickly. The people there are some of the friendliest you could find anywhere, not to mention that everyone is extremely likeminded. In my archaeology group we all shared similar interests and I have since made some lifelong friends from all around the world.
If you are considering this company I suggest sending them an email with all your questions, concerns, and anything else you may want to throw in there as they are quick to reply and help you. I had no idea what I wanted to do at first, but now that I'm home I'm so grateful for all the support I received from my first email to now. It was an incredible experience and I hope to volunteer with them again in the future.
