We don’t know the details, yet. If illegals have to go through background checks in both the US and their home countries, show continuous residence and steady employment in the US, and are prevented from voting for 10 years, I would be in favor of it.
1) They always say they are going to do background checks, and you would believe that? Do you know what a corrupt government Mexico, for example, has? Ever heard of "Mordida?" Ask Mexicans if they trust their own government.
2)"Continuous residence and steady employment...." I have serious doubts they will even try hard to prevent fraud.
3)"Prevented from voting 10 years..." So after 10 years leftists take control of all 3 branches of government forever. Sounds like a great plan.
