1、当错误的将缴费方式选成了西联汇款时，其实可以直接给这个邮箱FMJFEE.SEVIS@ice.dhs.gov发送邮件，请求帮助。我当时在网上查找发现很多攻略都说这个没有用，根本不会回复你，其实不然，被误导了很多天，多走了很多弯路！这个邮箱是会对你问题及时回复的！！！我是后来无路可走，发了邮件后发现是有恢复的！
2、按照邮件回复里面提供的方式是可以修改缴费方式的。具体如下：It is still possible to pay by credit cardas long as you have not already mailed your check or money order, or submitted payment via Western Union.To pay by credit card, go to the website:www.fmjfee.com.You must choose to create a new payment by selecting “Pay I-901 Fee.” Enter your SEVIS ID, Last Name and Date of Birth then select “Submit.”When the error message appears at the top of your screen, select the “Continue Making Payment” button. When you receive the pop up, select the “Make Payment” button. This will proceed to creating a new payment.When prompted, select “Credit Card” as the payment type. Once you have completed your transaction, you will be able to print your I-901 fee receipt.Credit cards that are accepted include Visa, MasterCard, American Express & Discover.
3、大概意思就是如果你的付费方式选成了西联可以通过再次提交“Pay I-901 Fee.”修改。首先，填好所需信息。然后点击“Submit.”提交。之后，选择“Continue Making Payment”（这步很重要不要选错）！再选“Make Payment”。再填写一下信息之后，就会有可以选择的“Credit Card” 付款方式。直接付款就可以了！
