You’ll want to check the specific terms of your offer, but you can generally exercise your NQSO any time after they vest. However, some companies may offer an early exercise provision that allows you to exercise before they vest.. You have until the expiration date, usually 10 years after vesting, after which any unexercised options will expire.
