Translation of Dozent

I have considered the option to bring my friends from other social networks and invite them to join here. They can develop better language skills here. I'd love to pursue that goal, but I want to write in English.
I usually do not travel, and if I do, then only to England, when I visit my parents who live in a suburb of London. I can not afford to travel too much, because it is a very large expense.
I am glad you know, I have learned Czech and my English is also not that bad, but we could speak in German. I got your message and I want to apologize again. Next time I will do it more accurate.
