Piscataway, located in Middlesex County, comprises 19.1 square miles, is 35 miles from New York City, and within 250 miles of one-quarter of the nation's total population.
Job seekers typically face age restrictions up until the age of 21 or 22. Many entry-level positions require young workers to stand at least 16 in order to gain employment, while others require applicants to be at least 18 years old upon hire.
There are certain laws called child labor laws that have a minimum age at which a person can begin to work. In Iowa (based on the Labor Laws Page) it says that anyone under 16 must have a workers permit to get a job. I believe the only exception for a 13 year old is if they work for THEIR family business.
