I have an opportunity to work part-time on a certain project from India as a freelance consultant but the Indian company said that they would pay for the services in Indian Rupees (INR) and to an Indian bank in India. The amount paid would be 20% of what is being paid by the current unemployment insurance company.

Is it okay for me to accept this offer and then present this job contract to RAV / swiss authorities to renew the Visa which is due on 30th June 2021?

I thought to check here before checking with my RAV consultant or Swiss Visa authorities just to be sure.

Does anyone have any ideas about such possibilities? Any help will be appreciated.

A contract from an Indian company, paid in Indian Rupees and into an Indian bank account may not work for the Swiss authorities to renew your permit. I could see them arguing that if everything else is in India, you should be there too. It's hard to argue you need to be a resident in Switzerland when your job that only pays 20% of RAV is not even located here.

I guess it won't even work in case of 40-50% and even if say that money will be transferred into Swiss bank
