Firstly, is the translation experience the only experience you have? If so, you couldn't have used it anyway as your primary NOC, as you need at least one full year of continuous work experience in one given NOC (and some other requirements as well...). So, I'm afraid if that's the case, you cannot use your translation experience it to immigrate. Unless you have another 1-year of continuous experience....
Do you have any other experiences that you had for at least one year?
