-No difference. Even if you efile, you still need to send the support documents to the address indicated on your efiled verification receipt immediately after efile. Print out the efiled verification receipt and enclose it with the support documents (put on the top).
如果填在紙,則相關的文件要寄往與我的I-797上標明的同一個處理中心,
而e-file則未必相同.
-Not the address as the paper file.
如何交費呢,
-When you efile, you need to pay the fee online during the efile using credit card or debit card, otherwise, you can not process the efile.
是否是將個人支票放入同一個信封即可?
如果e-filing,相關文件又如何提交呢?
-Send it to the address indicated on the efile verfication receipt.
還有就是,用我的H1 renew 的 receipt number,她們的H4 延期最長可以是多久呢?
多謝幫助!
