Last week we received an I-526 approval. This case received request for evidence. The USCIS asked about the source of fund. In particular, the $500,000 investment was from a Hong Kong company and the company did not have any business and tax records. To make things worse, the investment was wired into the company account from the company's CEO one day before the company wired the money to the EB5 petitioner.
After we responded to the RFE, USCIS approved I-526 petition within a week.
As of now, we never have had any I-526 or I-829 (remove condition) denials.
