I have a visit Visa for Abu Dhabi but I stay in...

As the question is not complete, I will answer on the clear part of it related to violating the visa and staying in a non-residence status. It is not allowed to leave the country until after paying the financial fines and therefore you may be subject to imprisonment and deportation after your obligation to pay fines. Referring to the regulations related to the residence of expatriates in the UAE:
Article 77
The Executive Regulation of Federal Law, stipulating that the competent Naturalization and Residency Department shall collect a fine of 100 AED for each day in which the alien resides illegally. As the penalty shall be calculated from the day following the expiration of the non-renewable visa and the expiration of 10 days for the renewable visas and seven days from the date of issuance of the exit permit for violators of the Aliens Entry and Residence Law.
Note that, the Nationality and Residency consider the 100 AED fine from the first day of expiration of all visa types even visit, transit, entry, tourist and entry permit to visit residents in the GCC.
Article 78
Of the same law stipulates that, except in the cases mentioned in the preceding article, the financial fine obtained by an alien for his illegal residence in the country after the expiration of his/her visa/residence permit, as it shall be calculated as the following:
· (25 AED) on every day of the first six months,
· (50 AED) for each of the next six months.
· (100 AED) for each day next to the year
