you're parents can sponsor son/daughter based on income. If they are US citizen, it will be faster.
@goupon, on US record, it shows that I was born in Phnom Penh. Does this mean I am a Cambodian citizen? How will the Cambodian government grant me Cambodian citizenship? I know some countries don't allow it, but is it legal here in the States to have dual citizenship?
I'm just preparing to relocate to Cambodia when zombies attack.
