Well, terrnis no better route, but if you want Quicker - adjusting here is the wat to go. That way you will not have to deal with the Department od State NVC and US Consulate in India. The process here will take 3-4 months. You will still have to file both petitions (not to mention all the other forms) concurrently. But the parents will be adjusted here without police certificates and other documents they would need for the consulate. Feel free to write to me directly at meltser@bmlaw.com
