After the student loan is paid off, you can apply to the lending institution and ask them to provide proof of settlement. Relevant repayment vouchers and loan contracts need to be provided as proof. After verifying the repayment record and confirming that the loan has been fully repaid, the lending institution will issue a settlement certificate. The certificate will clearly show that the loan amount and interest of all student loans have been paid off successfully, and confirm that there is no outstanding loan balance. You can fill in the application form and provide the required documents according to the requirements of the lending institution, so as to obtain the settlement certificate smoothly.
