A guarantor increasing the amount in the contract for their benefit

Q: What is the opinion of scholars on the following case? I want to bring my children and wife and, in order to do that, I have to conclude a contract with my surety, confirming that I receive a monthly salary larger than my real one. For instance, the contract attached to the papers that will be submitted to the recruitment office states a salary of 3000 Saudi Riyals, though he actually pays me 2000 Riyals. Does this involve a sort of telling lies? It should be noted that we do not deliberately intend to tell lies in this case; our sole purpose is to finish the papers in an official manner to allow me to bring my family.

A: This action involves forgery, telling lies and overriding the orders laid by the authorities to regulate the procedures of bringing over labor according to administrative requirements that should not be infringed.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
