Previous periods of unlawful stay in United States occurring prior to the aliens' 18th birthday do not count. Also, periods of unlawful stay occurring before Apr. 1, 1997 also do not count. If your son overstayed his status after Apr. 1, 1997 and was 18 years or more at that time, he may be inadmissible. However, if the consular officer decides that he is not eligible to receive a green card on this basis, he is qualified for a waiver. I suggest you should contact an immigration lawyer to help you sort this out.
