Duties of the State:
The duties of a state seem pretty simple, but performing them is not very easy. Every government in the world has to struggle immensely to perform its duties. Their duties are not just one-sided, which means that they have to take care of everything. It is the duty of the state to create opportunities for its citizens but also to maintain good relationships with its neighbors. This is why every government appoints various ministers. When the work gets divided, it becomes easier to manage. One of the most important duties of a state is keeping its citizens safe at all costs. For this, every country has various policies in place.
One way in which countries keep their citizens safe is by maintaining a strict visa and immigration policy. This helps them in keeping criminals away from their citizens. They ask for a police clearance certificate or PCC from visa and immigration applicants to make sure that only people with a clean background come to their country.
