Charter School Bonus

[B]anks and equity funds that invest in charter schools in underserved areas can take advantage of a very generous tax credit. They are permitted to combine this tax credit with other tax breaks while they also collect interest on any money they lend out. According to one analyst, the credit allows them to double the money they invested in seven years. Another interesting side note is that foreign investors who put a minimum of $500,000 in charter school companies are eligible to purchase immigration visas for themselves and family members under a federal program called EB-5.
