Czech as a foreign language

I would like to research and concern with the Czech as a foreign language in my bachelor thesis because I think that this topic is and will be still topical. Several ten thousands of immigrants direct to the Czech Republic every year. The minimum of them has been already equipped by basics of Czech and the most of them start learning Czech up to the destination. I would like to focus on the possibilities of teaching Czech which are offered in the Czech Republic. The next focus would be what sort of style and where Czech is taught in the foreign countries and how difficult it is for foreigners
