Language Barrier

Yes it will be a problem but am yet to experience.

I have experienced it many times. When I travel I often visit countries where I don't speak the local language. In Vietnam many people didn't speak English and we didn't speak Vietnamese. We went to a restaurant and we wanted to order to food, but they didn't understand what we meant. We had to use sign language. When I was living/working in Estonia I didn't speak Estonian when I arrived. My coworkers spoke English, but many of our clients didn't speak or understand English. It was hard in the beginning and I always had to ask my coworkers to translate for me. After two months I was able to understand a conversation in Estonian. People also understood what I said, but I made many grammar mistakes.

Language is a big problem when you go abroad,but i think it's very important that you can speak English,it will help you to solve a lot of troubles
