Nowadays, the investor visas take only brief processing times. An I-129 petition usually takes approximately six months to process. However, this still depends heavily on the amount of petitions of the USCIS service center during that time, as it is only the Center that processes your petition.
Fortunately, you can expedite the six months of processing by choosing for the premium processing service. This amazing option can cut short your visa processing time to just fifteen calendar days. If the USCIS does not meet this deadline, you will be refunded of your premium processing fee.
