Do you have atleast one utility account in your spouse name?
If not you should switch one account to spouses name.
We used to get our water bill with my name and my wife’s name listed on the billing statement. After they switched the billing system they removed my wife’s name from the bill.
While applying for OCI Card, we had to give proof for both mom and dads address.
Bank statement and phone bill are not accepted for address proof.
So we switched one account to wife’s name and had to wait till the next billing cycle to apply for the OCI card.
If you don’t have any utility bill on your spouse name, then you considering switching one account now to avoid any delay when you are under time crunch to apply for an application like OCI card or passport renewal.
