我表姐15年前，在国内因为贩**秽光盘，被判处传播**物品牟利罪，判刑四年。似乎本州刑法里没有这项罪名，那如何判断是否是道德堕落重罪？
目前已经美国连续合法居住满7年，一直是持学生身份。
我表姐四年前跟我表姐夫结婚，表姐夫是公民，已生育两子。表姐的父母投资移民美国，已转正式绿卡。现在表姐想申请临时绿卡，是不是必须先申请犯罪豁免？还有其他方法吗？申请绿卡时隐瞒行不行。背景调查会查出吗？
表姐是博士在读，学生签证还能维持好几年。她怕现在申请犯罪豁免被驳回，会导致马上被遣返回国。不但学业无法完成，也将面临跟家人的分离。
请问邓律师事务所有对移民和刑法都很熟悉的律师吗？是否可以代理这个案子的豁免申请？赢面有多大？谢谢

表姐犯罪时20岁，不属于未成年。

她想知道她是否适合美国的15年犯罪豁免移民法规所规定的要求，从而申请此项犯罪豁免。

I601 waiver - 15 year crime waiver

Status Waivers － 15 Year Rule
Finally, there is a general discretionary waiver based on the status of the immigrant rather than the crime. The offenses covered are crimes involving moral turpitude, multiple criminal convictions, prostitution or commercialized vice, assertion of immunity from prosecution, and simple possession of 30 grams or less of marijuana. There are two ways to qualify for this waiver.
The first involves convictions either for convictions for prostitution (regardless of how old) or convictions for certain other crimes that are more than 15 years old.
Criminal Grounds of Inadmissibility (Exclusion)
There are two waivers available under INA §212(h)(1). A waiver is available under INA §212(h)(1)(A) if the immigrant establishes that:
the activities for which the alien is excludable occurred more than 15 years before the date of the alien's application for a visa, entry or adjustment of status (unless the alien is excludable for prostitution under INA §212(a)(2)(D)(i) or INA §212(a)(2)(D)(ii), in which case the 15 year time period is not required),
the admission to the United States of such alien would not be contrary to the national welfare, safety or security of the United States, and
the alien has been rehabilitated.
