请问“由于美金兑换人民币日渐走低,我们在这张Invoice上的政府费用增加了600美金,当公司注册完成后我们将会多退少补.”这句话可以这样翻译吗?We have added USD $600 for the government fee on this invoice since the exchange rate of USD for RMB is going down from last year,we will refund for any over-payment or supplemental payment for any deficiency when the WFOE is established.
