Should I try for ivf?

Hi girls. I would like to hear your advices. I have been trying to conceive for 1yr+ … I have also made an appt with KKH and currently I have appointments with private clinic gynae and have done fertility test.. so far no much problem. If I go for kkh appt in later this year, during my first consultation with doc can I get an answer from doc that I can proceed with doc? Or I will not be allow with ivf? Any criteria to meet to try for ivf? Also, how long is the wait for ivf to start? Thanks thanks (:
