Your employer can ask for medical certification after 30 days, unless the leave period is expected to last more than 30 days, in which case the employer must wait until the leave period is up to ask for certification. An employer can ask for recertification at least every 6 months, and can ask for recertification more often if you request an extension of your leave, or if there are changed circumstances during the leave period.
