I'm wondering how long will i have to wear invisalign?

Depends : Treatment time depends on your teeth so this question cannot be answered here. See an invisalign provider for an evaluation and this will answer your question.

Ask the orthodontist: There is no magic answer to your question as it depends on your case. We've had patients wearing invisalign for only 3-4 months and others for 2 years. Varience is significant depending on your case. Ask your orthodontist-- they have developed the treatment plan for you.

Ask a Pro: No two malocclusions are identical. For the best qualified answer to your question see a fully qualified Orthodontic Specialist, who does only Orthodontic Treatment, for an initial examination (usually free) for the best answer to your question.
