回复：回复：Question about status?

863211, Thanks a lot. My 484 application is based on EB1B.
I got some information somewhere as follows. Section 104(c) of AC 21 permits EB-1, EB-2 and EB-3 applicants to seek an extension of their non-immigrant status when their green card applications are being held up because the per country limitations on a particular green card category are backlogged. To qualify for an H-1B extension in this case, the I-140 needs to be approved. Extension applications under this provision may be granted in increments of up to three years. And despite the reference in AC21 to only granted a one time protection under this section, the new memo makes it clear that a qualifying alien may be granted more than one extension under the provision. Based on the information, I am wondering whether my H1 can be extended for three years if my NIW is approved.
