What if your parents have been in the United States for over 15 years and have 3 kids born in the US, is there any way they can become legal citizens?

If your parents are caught, they may be able to obtain residence status through cancellation of removal which requires 10 years physical presence in the US, good moral character, and extreme and unusual hardship to a US citizen or permanent resident parent, spouse, or child under the age of 21 and unmarried. The application is made in an immigration court, and denial usually results in an order of removal. I note that there is a recent scandal involving unscrupulous consultants and attorneys who put in weak or meritless asylum claims with or without the knowledge of their clients to get them into immigration court because of the difficulty in getting DHS to issue Notices to Appear (NTAs) where individuals wish to affirmatively appear in court.. The practice is frowned upon by judges, government, and bar associations.  Otherwise your parents could wait until there is a change in attitude in this administration or any future administration that would allow a legalization of longtime residents. Your parents would probably be first in line for such benefit.
