Hello
My name is Kim and Im from Germany. Im 16 years old and I`m searching for a host family in Russia for the year 2016/17.If theres no family who would host me for a year ,I would also come for 2-3 month.Gladyl on reciprocity with another child.
If theres no other way I would also go to the United States.
