岳母B-2 延期I-539 被拒. 理由如下：
One ground of denial invovles the requirement that you have sufficient financial resources to support yourself for the proposed period of stay.
...
Included on Form I-539 are instructions to complete Part 4, Additional information relating to answers about emplyment and finances.
If you indicate that you have not been employed in the US since the last admision, you are required to fully describe how you are supporting yourself, to include the source, amount and basis for any income.
移民局随信附了I-290B, 允许一次机会(motion to reopen or a motion to reconsider)补材料. 这种情况下用 I-290B 补材料成功率有多少? 岳母没有收入, 我们可以给她提供经济担保, 除次之外我们还应提供什么文件. 另外，I-290B 表 part2 中， 应选D吗?(I am filing a motion to reopen a decision. My brief and/or additional evidence is attached).
先多谢了。
