Steps to Withdraw PF from an Exempted Trust
You might have left the organization in 2015, but you might still have your PF accumulation slips/statements. You need to get in touch with your organization and fill out the relevant forms. The application has to go through them to the trust. Seeing the merit of the case, you may get a loan.
You have not provided any details such as the length of service, whether you have previously taken any loans, whether you are currently working, and if so, whether they are deducting PF, etc. This information would have enabled us to give a more precise answer.
