With the amendments, the law now requires investors to obtain preliminary approval from the investment agency. If you make sure that your investment is legally compliant, the chances of success will be close to 100%. What you need to do, however, is to process your application without any corners being cut, so you won't get any unpleasant surprises. So, the answer to your question is very easy: just be legally compliant and follow the regulations. That’s it, nothing more, nothing less.
