Can you be deported in RPI status?

Well, the reality of the United States law is that you can be deported even after naturalization to US citizenship (assuming that you naturalized using false evidence or lied about your background, though, deportation of naturalized citizens is rarer simply because most liars are caught before their naturalization), but it is every easy to deport green card holders if they commit a felony.  It is, therefore, understandable that individuals in Registered Provisional Immigrant (RPI) legal status under the provisions of the Border Security, Economic Opportunity, and Immigration Modernization Act of 2013 (BSEOIM) will have a much lower bar for deportation.  The clear message is that if you love America and want to build a good life here, always follow the law.  Take time to learn American laws, and if in doubt, don't do it.  What might be perfectly acceptable in your native country (bribes, playing loud music on your own property, settling disputes through violence, or beating women up because you look down upon women) are very serious crimes here and the more effort you make to understand American society and culture, the better you would do.  Thus, it is not just felonies that you should avoid, just make sure that you never get into trouble with the law, and that means not even speeding.
