Passport and B2 Visa damaged - Please suggest

[vsv]

My mother-in-law's passport and B2 visa got damaged (photo on the visa page faded slightly but everything remains intact) as the passport was washed out in a car accident.
At the immigration clearance the officers told her to get the new passport and visa and the trip got cancelled.

Question is

If she can secure a new passport thru Tatkal option, should she go thru Visa appointment for stamping again?

Please suggest.

Yes ...

... it's in your best interest to get the visa stamped again on the passport.

I am not sure but you may not have to pay the full fees and there won't be any interview. Check it out.

Good luck.

You have to pay new visa fees for damaged visas/passports. The old passport has to be carried but the interview will be simple.
