B1/B2 is the business visa
The famous and standard tourist visa a.k.a B1/B2 is also the business visa. The time you will be aloowed to stay in the US will depend on what the border officer decides. It is common to give business visitors a shorter time than to tourists. However, it is also common to have business visitors fly in and out of the US every two weeks.... Under the B1/B2 visa you may do any business activity in the US that does not qualify as employment by an american company.... which basiclly mean - everything that is legal. If you are looking for "trader visa" - E1 is the letter. E2 is not open for Israeli citizens. Good luck.
