Enroll in a university course. In Omaha, Creighton University (creighton.edu) offers beginner and intermediate level Russian classes. There are also a number of courses available in Russian history, politics and culture. Contact the university and ask about the possibility of auditing a course if you don't want to enroll in a full university program. This will allow you to sit in on a single class for a fee.
Join a Russian club. Clubs such as the one at Creighton University allow students to gather and share Russian language and culture and take part in a number of cultural events.
Take private lessons. Enrolling in university courses can be expensive and time-consuming. Classes such as the ones available at Listen & Learn (listenandlearnusa.com) are available for people in Omaha who want to learn Russian.
Find a private tutor. Most cities have ads for private language tutors posted in cafes, business directories and on university bulletin boards. Furthermore, online resources such as Wyzant (wyzant.com) can be used to search for tutors in Omaha. Tutoring is a good option if you only have a couple of hours a week for study, or if you want to add some additional hours to your study schedule.
Try a language meetup. If you don't have the opportunity to speak a foreign language, you will find it difficult to improve. One way to ensure that you speak Russian regularly is to form a language meetup group. You can post notices on public bulletin boards or use a website such as Meetup (russian.meetup.com), which allows users to find other people in Omaha who want to practice speaking Russian.
