The dispute appears to be over the added content, "
A source says "civil violation".  Terjen keeps changing it to "civil infraction" and it's not at all clear if "civil violation" is the same thing as "civil infraction" - it's safer to stick to the original wording of the source.
"this civil offense should not be construed to diminish or qualify any other penalties to which an illegal alien may be subject" was added with a reference to the Immigration and Naturalization Act section 274D where residing in the US is identified as a civil offense, it also adds, "Nothing in this section shall be construed to diminish or qualify any penalties to which an alien may be subject for activities proscribed by section 243(a) or any other section of this Act".  Terjen appears to believe that the way I summarized that statement constitutes original research.  I have posted a question in the Wiki Law project to get outsider opinions on whether I properly summarized it or not.
Terjen continues to put the statement that residing in the US is a civil offense at the top of the paragraph.  Considering that most illegal immigrants are sojourners, not residents, this edit makes no sense and I've put the paragraph's subject sentence, "Various unlawful immigration-related acts, depending on the circumstances, may be criminal and/or civil offenses", at the beginning.
Terjen edited the word "crime" to "misdemeaner", but provided no source for doing so.  I reverted it.-66.194.62.5
