You may see improvement in a month or two if you really try hard, employ the effective way of learning along with a fairly good command of English. Unlike business related positions, IT jobs usually don't require excellent verbal skills as long as you are capable to read and write well, and orally make yourself understood. I know a few IT guys which are far less qualified than me in terms of English specially spoken but they found their jobs quickly and are doing well. Don't be scared. Language is not really the number one issue. The skills required play the key role.
