BART is a US Regional Center, approved by the US Citizenship and Immigration Services (USCIS).
The USCIS created this programme intending to attract foreign investment to underdeveloped American regions. And naturally, there should be an appropriate reward for such investment – citizenship. That said, an important factor for the US in concluding such agreements with investors is the level of risk. Contracts which offer investors some guarantee may be met with less enthusiasm by the US authorities. It is therefore important that there are no direct guarantees written into the contract, so as not to jeopardize your citizenship application later on.
