如果你在美国没有银行帐号，需要使用中国的银行来做资金证明，所有非英文资料需要翻译成英语。
USCIS 官方的I-539 填写指南对此说明如下：
Translations. Any document you submit to USCIS with information in a foreign language must be accompanied by a full English translation. The translator must certify that the English language translation is complete and accurate, and that he or she is competent to translate from the foreign language into English.
建议找一个中英双语的朋友做 certification，参考我之前为结婚证做的「公证」：
CERTIFICATION BY TRANSLATOR
This is to certify that I am competent to translate from Chinese into English and that the above translation is accurate.
