some points
kingno1, here's my response (just for your reference, not professional at all!!!! you need to check with a lawyer.) to your questions:
Looks like it takes abt 3-4 months for that. Why is EB3 ahead of EB2 dates?
>>Maybe there are fewer EB3 cases than EB2. However, it seems that both take about the same length of time.
Also, when do we have to specify Consular or 485? Is it during the time when we file for 140?
>>On I-140 form you need to indicate I-485(AOS or adjustment of status) or CP (consular processing). I heard indicating CP can be easily transferred back to I-485 if you want to, but it's very time-consuming the other way around. Again, check with a lawyer.
Another thing is which one is advantagious, consular or 485?
>>If one is definitely better than another, you will see everybody going that direction. I heard CP is faster (by about 3 or 4 months?), especially for Indian nationals. However, the risk is also higher since once rejected, there's little chance for a review. Whereas 485 can stay in US and hire a lawyer to appeal if rejected. Also, 485 saves airfares or time spent on travel.
I am from Hyderabad, so, Do I have to go only to Madras if I choose consular?
I am looking on some other thread and they are sayingthat for Madras, 485 is much better than Consular due to some additional filing papers?
And finally, someone in our office was mentioning that there is some simultanious 140 and 485 processing? Is there a chance that it can be true?
>>No clue about these questions.
