Apparently one of the provisions in the new bill would make it so that illegals could prove that they have been in the country for at least five years and thus be eligible for citizenship. To prove this residency, illegals can provide electric utility bills or other similar documentation. I am not sure who keeps their utility bills for five years plus, but there is another problem. Whatever one thinks about illegals becoming citizens, there is a side issue of possible forgery regarding these documents. An incredibly straightforward solution is that any such documentation would have to be checked by the screening agency with the company that issued the original document and that there would be a criminal penalty if the company altered documents. If there are additional concerns, possibly three types of documentation could be required. Pretty simple, and it would solve many concerns. For some reason though I don't think that the bill will contain this provision.
