At present, it is impossible to study abroad in this epidemic situation. Has the state issued a policy that the deposit paid to overseas agencies can be refunded?

It depends on whether your contract agrees to breach the contract. If so, the contract can be executed as agreed. Otherwise, you can charge a specified fee and return the balance to the other party. Of course, my personal understanding is that since you have completed all the obligations in the contract, the other party's unilateral request for refund of the deposit should not meet the requirements of the contract and can be rejected. We won't know until we see your consent form. The above comments are for reference only.
