Is GOCI certificate mandatory now for permanent family visa

Someone told me they did not accept his salary letter from employer and asked for GOSI certificate instead with gross salary details.
I am planning to apply for my wife's permanent visa but my salary is 2000 according to GOSI system. What can I do?

Yes at the most right now they will ask for GOCI Certificate instead.. You have to ask your employer to modify your real salary at GoCI first then print the Certificate .

Thank you very much for your help, Can I try first going without the GOSI, if it gets rejected can I visit the very next day if I get an appointment?
Also, employer can change the salary in GOSI anytime? I read it can only be done in muharram.

I can't be sure if that will work or not .

the employer can change the salary in GOSI but not always
