There is no invoice for the deposit, and foreign exchange settlement is not allowed. The rent is ok. I don't know where the reference documents are, because after the settlement of foreign exchange, these funds must be tracked. Proof of where to use the settlement money next time, as well as related invoices and payment vouchers, should be handed over to the bank. Your deposit will be refunded to your company in the future. It is out of the question. This is the rule. There is no way.
