请教各位前辈了：
我是13年12月提交父母移民申请，大概去年6月份妈妈被查出肺癌晚期。目前我正在补经济担保的材料中，估计还得要半年的时间吧？
我想知道：
1、可以现在换签证申请来美国看病，这样会快很多吗？
-Because your parents have immigration intent, it is very difficult (nearly impossible) for them to get the regular B-2 visa. But you may try to see whether your mother can get the visitor visa for medical treatment in US. Read the following links for some basic information:

2、可以同时申请这两种签证吗？
-What kind of visas do you mean?
3、我妈妈的这种病签过的机率会很低吗？
谢谢大家了！
