Changing Jobs on an H-1B During Your Mortgage Process (2026)

Quick answer (updated October 2026): You can change jobs on an H-1B during a mortgage, but timing decides whether it's a non-event or a lost house. AC21 portability lets you start once the new petition is filed, and lenders re-verify employment before closing. Tell your loan officer before you accept the offer, because base pay, RSUs and bonus history may change your approval.

It happens every hiring season. You're under contract on a house in Bothell or Frisco, and a recruiter calls with a 20% raise. Or a layoff rumor makes you start interviewing quietly. Either way, the mortgage is mid-stream.

Job changes during a loan aren't forbidden. But they collide with two systems: the lender's employment verification and the H-1B transfer process. This guide covers how each works, a stage-by-stage timing table, and the specific income items that often disappear when you switch.

What AC21 portability means for your mortgage

Under AC21 portability, an H-1B worker can start working for a new employer as soon as the new employer files the H-1B petition; you don't have to wait for approval. For the immigration side, that's flexible. For the lender, it creates a document question.

During an h1b transfer during mortgage, your file may show:

• Your old I-797 approval for the prior employer

• An I-797C receipt for the new employer's petition

• An offer letter or new paystubs

Fannie Mae's B2-2-02 lets the lender decide how to document legal presence, and many lenders accept a receipt with the prior approval. Some lenders want the new approval notice before closing; that's an overlay. Our guide to getting a mortgage with an H-1B extension pending covers receipt-only files in detail.

Lenders re-verify your job right before closing

Every conventional loan includes a final employment check shortly before closing, usually a phone call to HR or a database verification. If your old employer reports you as terminated and the file still shows that job, the loan stops.

This isn't a trap; it's the system working. The fix is disclosure. If your loan officer knows about the switch early, the file can be rebuilt around the new job instead of failing at the finish line.

Qualifying on a new job: the offer letter rule

Fannie Mae's employment offer rule (B3-3.3-03, updated Oct 7, 2026) gives lenders two ways to use income from a job you haven't started or just started:

	Option 1: Paystub before delivery	Option 2: No paystub before delivery
Key requirement	Lender obtains a paystub before delivering the loan	Non-contingent offer + verbal verification
Start date window	None	No earlier than 30 days before note date, no later than 90 days after
Transaction and property	Per the guide and lender	Purchase, 1-unit primary residence only
Income used	Per the guide and lender	Fixed base income only
Employer	Per the guide	Not family or an interested party
Extra reserves	Ask your lender	6 months of housing payment OR all debts through start month + 1

For an H-1B worker, "non-contingent" can be tricky. If your offer says "contingent on H-1B approval," expect questions, and get the I-797C receipt into the file quickly. Lenders differ on how they treat that language. More detail is in our post on getting a mortgage with an offer letter.

When to change jobs on an H-1B during a mortgage: timing table

Stage	Risk of switching	What to do
Before pre-approval	Low	Switch first, then apply with new paystubs and offer
Pre-approved, not under contract	Low to moderate	Tell your LO; re-run approval with new income
Under contract, before underwriting approval	Moderate	Disclose immediately; provide offer, receipt and first paystub
Conditionally approved	High	New income must be re-underwritten; closing may slip
Clear to close	Very high	Wait until after closing if at all possible
After closing	None for the loan	Your loan is done; the switch doesn't affect it

The safest move: if you get an offer while under contract, ask the new employer for a start date a week or two after your closing date. Most employers accommodate that once you explain.

What income can disappear when you switch

Base salary moves cleanly if the new job pays the same or more in the same field. Other income doesn't always follow you.

• RSUs: Fannie's RSU rule (B3-3.3-07) requires time-based RSUs to have 12 months with your current employer. Leave, and your old RSU income stops counting; your new grant won't count for a year. Sign-on RSUs aren't eligible at all. Our RSU income guide walks through the formula.

• Bonus: A bonus history at your old employer doesn't automatically carry to the new one. Lenders may not count a new bonus until you've received it. See our post on sign-on, relocation and annual bonuses.

• Commission or variable pay: Usually needs a fresh history.

Worked example

Say Rohit, a hypothetical H-1B engineer in Seattle, earns $185,000 base plus RSUs vesting at about $60,000 a year. He qualified for a $640,000 loan on that income. Then a startup offers $205,000 base with a sign-on RSU grant.

	Old job	New job
Base salary (monthly)	$15,416.67	$17,083.33
RSU income counted (monthly)	~$5,000	$0 (sign-on RSUs ineligible)
Total qualifying (monthly)	~$20,416.67	$17,083.33

His qualifying income falls by about $3,333 a month despite the raise. Principal and interest on $640,000 at 7.40% (Freddie Mac weekly average, Oct 15, 2026 — illustration only, not a quote or offer) is $4,431.23. He may still qualify, but with less room, and possibly not at all if he has other debts. Run the numbers before signing.

Talk to a loan officer who's seen this before: Got an offer while under contract? Send us both offer letters before you sign anything. We'll run your approval on the new income and tell you whether to switch now or after closing.

A five-step plan if you're switching mid-loan

1. Tell your loan officer first, before you accept or resign.

2. Get the offer letter with title, base salary, start date and any contingencies.

3. Confirm the H-1B filing timeline with the new employer and your immigration attorney; get the I-797C receipt as soon as it's issued.

4. Pick a start date that works with the closing date or the 30/90-day window.

5. Hold reserves in case Option 2 applies or your income takes time to document.

Frequently Asked Questions

Q: Can I change jobs on an H-1B while my mortgage is in process?
A: Yes, but tell your loan officer before you accept. AC21 portability lets you start once the new petition is filed, and lenders can often use an offer letter, new paystubs and a receipt notice. Switching after clear to close is the riskiest timing, since the final employment check can stop the loan.

Q: Will my lender find out if I change jobs before closing?
A: Yes. Lenders re-verify employment shortly before closing, often by calling HR or checking an employment database. If your old employer reports you as no longer employed and your file still shows that job, closing stops. Disclosing early lets the file be rebuilt around the new job.

Q: Can I close with only an H-1B transfer receipt notice?
A: Often. Fannie Mae lets lenders decide how to document legal presence, and many accept your prior I-797 approval plus the new I-797C receipt. Some lenders require the new approval notice before closing. Ask about this overlay as soon as you know a switch is coming.

Q: Do my RSUs still count if I change jobs before closing?
A: Usually not. Fannie Mae requires time-based RSUs to have 12 months of history with your current employer, so RSU income from your old job stops counting when you leave. Sign-on RSU grants at the new job are not eligible. A raise in base pay may not offset the lost RSU income.

Q: Should I delay my new job start date until after closing?
A: If you're under contract, often yes. Asking for a start date shortly after closing is the cleanest way to avoid re-underwriting. If the employer can't wait, Fannie's offer-letter rule may still let you close if your start date falls within the allowed window and you have extra reserves.
