scam / fraud issue

is filling a fraud in US can deport a filipina?

she married to a US citizen last 2002 but she tell the foreigner that she only has 1 kid but the truth is she has 3 kids now a teenager. before she always ask money from a guy. the girl divorced the guy in US cuz she already has a paper to travel in USA, she travel to US without even telling to the guy. the guy was surprised about the news that his wife is already there and they never meet never been acted like husband and wife and even they are divorced the girl still asking money from him. we have lots of photo proof that the girl has 3 kids here in philippines,and documents of money transfer too.

the act of demanding money due to a relationship and telling that she only have one kid where in fact she had 3 does not constitute fraud...
only for civil suit for damages and collection, but no deportation can be had...
