That's close, but it may not be enough. The law does not say how much it should be, but most attorneys will not take a case that has less than a $200,000 investment. Why? Because while some cases for less than that amount have been approved, the chances of approval are low. Here is an official link to the E-2:
Again, you won't find a minimum dollar amount, but $200,000 or more is a safer amount. The money must be invested and at risk before the visa can be issued. It must be invested in an active business where you will be involved in day to day decisions. So for example, you just couldn't be a house and that would be enough. Also, there is no minimum amount of employees you must hire, but your company should produce enough to employ you and perhaps one or two other U.S. workers. Employing your family does not count.
An L-1A is a possibility if you have a business outside of the U.S. for 1 year or more and you would be investing $100,000 or more in an active business in the U.S., but you must continue to run both companies. Here is a link:
Please let me know if you have any additional questions. I would be happy to answer them for you without additional charge, if not, please do not forget to click ACCEPT. I am not paid a salary. Clicking accept is the only way that I can get paid for helping you. When you click accept, you are not charged again and we can continue to communicate without additional charge if you have a few follow-up questions. If there is a delay in getting back to you it is either because I am answering other questions or I had to log off, but I will be back with you as soon as possible. If you would like to request me in the future, just put my name on the subject line. Positive feedback for my service to you (not the state of the law as it is) is always appreciated as well as any bonus if you think I deserve it. Thank you.
