If your i94 date is same as your OLD passport expiry date and now you need to change/extend the i94 date based on your new renewed passport, you can visit SAN Diego CBP office at US Mexico border.
Travel to Tijuana Border, San Diego for i94 extension
You may or may not have to cross the border to correct the I-94 date at this border depending on CBP officer that you see. The CBP office is inside US territory.
San Ysidro i94 update opening hours
The i94 correction / extensions are done 24x7.
San Ysidro Land Port of Entry – West Pedestrian Facility - PedWest
This port of entry is just beside the Premium Outlets.
PedWest US exact Google map address:

Thanks to @vinodnama for sharing the exact PedWest address after he got his i94 extended.
East Pedestrian Facility does not fix i94 now.
i94 extension fees
$6 - Cash or Online
i94 extension fees CASH
Look for i94 permit sign on the building entrance or door.
Once you are in, you can make the payment and wait for your name to be called.
The waiting lines may be long at CASH payment counter.
i94 extension fees ONLINE
So, it is advisable that you make the payment online at CBP website with ‘Land’ border entrance option.
This payment is valid for 7 days meaning that you can pay online and visit the border for i94 update anytime during those 7 days. There are no refunds if you miss the 7 day deadline.
You will need to fill your NEW passport number on CBP website while paying for fees as this is the passport you will use to enter US now.
If your new passport number is not accepted by CBP site, you can use your old passport number as well.
Both options work fine for i94 fees payment.
i94 extension interview questions
The interview would be same as you would have faced (by immigration officer) while entering US at any port of entry.
Documents required for i94 extension
Original Approved i797.
Your Old and New passport.
Your US address proof - Could be any utility bill, your driving license, state ID, EAD card etc.
i94 extension approval
Once the officer is satisfied, he will take your finger prints and a picture. This is exactly same as what happens at any other port of entry (at airport).
You will get paper I-94.
He will also stamp your passport with new dates as applicable per your approved I797 validity.
i94 extension at San Diego Processing time
The whole process can take anywhere between 15 min to 1 hour. So be prepared.
No appointment is required. Neither do they have any option of appointments. It’s a walk in facility.
Once i94 is issued, it is updated immediately at CBP website too.
New i94 record is attached to OLD passport number
This is fine. When CBP extends the i94 based on your renewed passport, they usually attach it to the same OLD and expired passport number.
So, if you search online on their website, you will be able to pull your new and updated i94 based on your OLD PASSPORT number.
Also, both “Most Recent Entry” date and “Admit Until” on I-94 are updated.
There is no need to worry here.
Tijuana Border Car Parking
You can park your car at the outlets mall
4463 Camino De La Plaza, San Ysidro, CA 92173
Or at this closest parking lot:
4570 Camino De La Plaza San Diego, CA 92173
Both are at about about 2-3 minutes walking distance from San Ysidro Land Port of Entry – West Pedestrian Facility.
Mexico immigration is NEVER touched
You do not need to go through Mexico Immigration at all.
You just cross the US border (step into Mexico land) and then immediately turn back to enter USA.
In this whole process, you never even see any Mexico immigration counter.
If US does not let you re-enter from Mexico border?
In the unfortunate case of rejecting your entry into the USA (it is possible), you will need to go into Mexico as that would be the only option left for you.
Your US visa/ i797 is valid to enter Mexico. So, no need to worry about applying for a Mexico visa separately.
Crossing the border is your choice
If the immigration officer asks you to cross the US border and re-enter to update your i94, then it is your choice to take that chance or not.
They do NOT force you. You are still on US side and safely come back to your home (if you decide to NOT cross the border) and use other methods to extend your i94.
