Crime prevention is the attempt to reduce and deter crime and criminals. It is applied specifically to efforts made by governments to reduce crime, enforce the law, and maintain criminal justice.
A security officer (or security guard) is a person who is paid to protect property, assets, or people. Security guards are usually privately and formally employed civilian personnel. Security officers are generally uniformed and act to protect property by maintaining a high visibility presence to deter illegal and inappropriate actions, observing (either directly, through patrols, or by watching alarm systems or video cameras) for signs of crime, fire or disorder; then taking action and reporting any incidents to their client and emergency services as appropriate.
Until the 1980s, the term watchman was more commonly applied to this function, a usage dating back to at least the Middle Ages in Europe. This term was carried over to North America where it was interchangeable with night-watchman until both terms were replaced with the modern security-based titles. Security guards are sometimes regarded as fulfilling a private policing function.
The E-2 Investor Visa allows an individual to enter and work inside of the United States based on an investment he or she will be controlling, while inside the United States. This visa must generally be renewed every five years, but there is no limit to how many times one can renew. The investment must be "substantial". Investor visas are available only to treaty countries, which include countries like Albania and Senegal, but do not include Brazil, Russia, India and China.
For new startups, the investment must be large enough to start and operate the business. The amount of investment varies on the type of business. The investment will not be considered substantial if it is not large enough to capitalize the venture. The USCIS will use an ‘Inverted Sliding Scale’ to determine whether the investment is substantial in proportion to the overall cost of the enterprise.
