我母亲来美探亲近半年了，想申请延期居留。我看了一些帖子，总结了一下，似乎file I-593时需要很多材料，请问这样是否齐备了？谢谢！
- I-539表
- MONEY ORDER US$290元（请问支票行不行？-Fine）
- 存款证明-If you work, you may just provide your employment verification letter from your employer instead of bank statement.
- I-134表（请问I-134是必需的吗？）-Yes.
- 旧的I94卡 (记得先影印一份下来)-Print out your mother's latest I-94 at this website and provide it: https://i94.cbp.dhs.gov/I94/consent.html;jsessionid=Vh58Ww2Sgc1TTMh5lD1MKJRY10XMvBCpyzGH7Zb4BQktXJl2NwZR!1808615784
- 回程机票证明(它可能会给你机票上的时间所以可以晚点OK)-Not need to provide it if you don't have it yet (it is not required).
- 护照和VISA 页和入境章页 影本
- 给USCIS的信
- 还需要其它材料吗?-Check I-539 Instructons.
