How Long Does FMLA Approval Take? The 5- and 15-Day Rules

Last reviewed October 2026 · General employment information, not legal advice. Laws vary by state. See our Disclaimer.

You handed in your paperwork nine days ago. Nobody has said yes, nobody has said no, and your surgery is in two weeks. HR says it’s “being processed,” which tells you nothing.

There are actual deadlines, and most of them are your employer’s. Here they are.

The Short Answer

Your employer has five business days to give you the decision once it has enough information to make one. The reason approval often takes three or four weeks is the step in the middle: if a medical certification is required, you get 15 calendar days to return it, and the clock on the decision generally doesn’t start until your employer has a complete one.

So a straightforward request with no certification needed can be decided in about a week. A request involving a serious health condition usually runs three to four weeks end to end. Anything substantially longer than that means a deadline has been missed, and it is probably not yours.

The Full Timeline

Step	Whose deadline	How long
Tell your employer you need leave	Yours	30 days ahead when the need is foreseeable; as soon as practicable when it isn’t
Eligibility Notice and Rights & Responsibilities notice (Form WH-381)	Employer’s	5 business days
Return the medical certification (Form WH-380-E or WH-380-F)	Yours	15 calendar days
Written notice telling you what’s missing, if anything	Employer’s	At the time it reviews the certification
Fix an incomplete or insufficient certification	Yours	7 calendar days, in most circumstances
Designation Notice — the actual decision (Form WH-382)	Employer’s	5 business days

Every form in that table is on the Labor Department’s Wage and Hour Division forms page. Your employer may use its own versions, which is allowed, but they have to collect the same information and give you the same notices.

What Your Employer Owes You in Five Business Days

This is the deadline most workers don’t know exists, and it’s the one to check first.

Per the Labor Department’s guidance on employer notification requirements, the eligibility notice must be provided “within five business days of the initial request for leave or when the employer acquires knowledge that an employee leave may be for an FMLA-qualifying reason.” The same five-business-day window applies to the designation notice, which must be in writing, “absent extenuating circumstances.”

Two things follow from that wording.

The clock starts when your employer acquires knowledge, not when you fill in a form. If you told your supervisor you’re having surgery and will be out for a month, that’s knowledge. You don’t have to say the letters FMLA.

And the designation notice has to tell you whether paid leave will be substituted — whether your PTO and vacation will be burned alongside the unpaid FMLA leave. That’s covered in whether your employer can make you use PTO during FMLA leave, and it’s the single most expensive thing buried in that notice.

Why It’s Probably Waiting on the Certification

If your approval is slow, the certification is usually why.

Your employer can require a medical certification from your health care provider. Once it does, the Labor Department’s certification guidance says you “must provide the requested certification to the employer within 15 calendar days” of the request.

Fifteen calendar days, not business days. And that window belongs to you — but it’s also where most of the delay lives, because it depends on a doctor’s office returning a form. Get it to them the day you receive it, and follow up at the one-week mark. Nothing else in this process is as much within your control.

If Your Certification Comes Back Incomplete

Your employer can’t simply deny you for a flawed form. It has to tell you what’s wrong, in writing, and give you a chance to fix it.

The standard is specific. A certification “is considered incomplete if one or more of the applicable entries on the form have not been completed.” A certification is insufficient if the information is vague, ambiguous or non-responsive — hazy answers that don’t actually answer the question.

Once your employer gives you written notice of what’s missing, you get “seven calendar days in most circumstances” to supply it.

So if a form comes back and you hear nothing, or you hear “it’s not good enough” with no written explanation of what’s missing, that’s a step your employer skipped rather than a reason you’re denied.

Second and Third Opinions, and Who Pays

If your employer has reason to doubt a certification that is complete and sufficient, it can require a second opinion from a provider it chooses — though generally not one it regularly employs.

If the second opinion conflicts with the first, a third provider can be required, and that one must be chosen jointly by you and your employer. The third opinion settles it: “The opinion of the third health care provider is final and must be used by the employer.”

You don’t pay for any of this. “The employer is responsible for paying for the second and third opinions.”

Each of these adds time, which is the honest answer to why some approvals take six weeks rather than three.

Can Your Employer Call Your Doctor?

Yes, within limits — and one of those limits is worth memorizing.

Your employer “may contact the health care provider to authenticate or to clarify a certification.” Authentication means confirming the form really came from that provider. Clarification means understanding the handwriting or the meaning of a response. It does not mean asking for additional medical information.

And who may make that call is restricted: a human resources professional, a leave administrator, a management official, or another health care provider. The rule that matters most to you is stated flatly — “the employee’s direct supervisor may never contact the employee’s health care provider.”

If your manager phoned your doctor’s office, that’s a violation on its own, separate from however your leave request turns out. Write down the date and who you heard it from.

How Often Can They Make You Recertify?

Generally no more often than every 30 days, and only in connection with an absence. Regardless of the condition, your employer may also request recertification every six months.

If recertification requests are arriving more frequently than that, or arriving with no absence attached, that’s a pattern worth documenting — particularly if it started after you raised something else.

What If Your Employer Blows the Deadline?

Missing the five-business-day notice deadlines doesn’t automatically win you anything, but it matters when it costs you something.

The practical question is whether the failure harmed you. If you’d have scheduled surgery differently, taken leave at a different time, or arranged pay differently had you been told on time, that’s the kind of harm that supports an interference claim. A notice that came three days late and changed nothing is unlikely to go anywhere on its own.

What it does do is establish a pattern, and patterns matter when a leave request eventually gets denied or when you’re disciplined for absences that should have been protected. Keep every email, note every date, and save the envelopes.

If the leave is denied outright, whether your employer can deny FMLA leave covers the grounds that are and aren’t legitimate.

Can You Take Leave Before It’s Approved?

This is the question underneath most searches on this topic, and the answer is reassuring.

Your protections don’t switch on when a form is stamped. If your situation qualifies and you’re eligible, the leave is FMLA leave — the designation is your employer recognizing that, not granting it. Employers can and do designate leave retroactively.

So if your surgery is Thursday and nothing has been approved, take the leave, keep notifying your employer, and keep every record. Being fired for absences that later turn out to have been FMLA-protected is a serious problem for an employer, and whether you can be fired while on FMLA covers what that looks like.

Most people waiting on FMLA approval assume the silence means something is wrong with their request, when the far more common explanation is that a form is sitting on a desk at a doctor’s office and nobody has told anyone. Count the business days since you first told your employer you needed leave, and count the calendar days since you were handed a certification form — those two numbers tell you whose deadline is being missed. If it’s been more than five business days since your employer had what it needed and you still have nothing in writing, that’s the question to put in an email today.

Frequently Asked Questions

How long does FMLA take to be approved?

Your employer has five business days to issue the designation notice once it has enough information to decide. If a medical certification is required, the realistic end-to-end time is three to four weeks, because you get 15 calendar days to return it.

How long does FMLA take to process after I turn in my paperwork?

Five business days from the point your employer has a complete certification, absent extenuating circumstances. If the certification was incomplete, the clock effectively pauses while you’re given written notice and seven calendar days to fix it.

How long do I have to return the FMLA certification form?

Fifteen calendar days from when your employer requests it — not business days. If it comes back incomplete or insufficient, you get another seven calendar days in most circumstances after written notice of what’s missing.

Can I take FMLA leave before it’s approved?

Yes. Protection depends on whether the leave qualifies, not on whether a form has been processed, and employers can designate leave retroactively. Keep notifying your employer and keep records.

Can my boss call my doctor about my FMLA paperwork?

Your employer may contact your provider to authenticate or clarify a certification, but only through a human resources professional, leave administrator, management official or another health care provider. Your direct supervisor may never contact your health care provider.

What if my employer never responds at all?

Count the business days from when it first knew you needed leave. More than five with nothing in writing means a missed deadline. Put the request in an email, keep the record, and if it stays unanswered, the Wage and Hour Division takes FMLA complaints at no charge.
