Free Migration has been slowly restricted throughout recent history due to the inevitable progression of society, causing more independent societies to create tighter laws, policies, and regulations concerning immigration. With nations closing themselves off and shutting their borders from non-residents, it is difficult for free migration to become secure, as well as having members of society prioritize an institutional issue such as this.Immigration officers and agents must maintain a code of conduct based on policy to provide equal treatment to any and all immigrants. Officers must put their political views behind them and revert to policy law; leaving behind their personal moral conflicts and ethics to abide by law and policy. Political philosophers focus on free movement as a human right and aid for those in poverty or serious global inequality.
