Does my son need to apply I130 and pay filling fee again and how long is the application still valid?

Generally, a Form I-130 Application for Relative Alien may be filed and approved regardless of whether the beneficiary remains subject to the 10-year bar. Although not clear from your message, I presume that only the consular processing step was denied, and the Form I-130 application remains pending or perhaps has been approved. If you had been represented by an immigration attorney, you could have avoided the costs and waste of time involved in seeking consular processing before you were eligible, and it would be wise to engage an immigration attorney now, who after learning all of the relevant information about you and your immigration history would be able to advise you about the most appropriate steps to take this year to achieve your goals as promptly as possible.
