EB-1 chargeable to mainland China has been retrogressed in recent visa bulletins, although the China EB-1 final-action date has generally moved more meaningfully than India's. The procedural mechanics are the same: EB-1A is self-petitioned, the I-140 can be filed regardless of priority-date currency, and what requires currency is adjustment of status or consular processing. For Chinese-born petitioners, the EB-1A inquiry usually arises against a background of an existing EB-2 or EB-3 filing, an O-1 or H-1B status, or a research or industry posting in the United States that has matured to the point that a self-petitioned filing is realistic.
Chargeability is determined by country of birth under INA § 202(b) [8 U.S.C. § 1152(b)], so a petitioner born in mainland China who later acquired citizenship elsewhere remains chargeable to China for visa-bulletin purposes. Chinese-born petitioners with spouses born in Hong Kong, Taiwan, or other "All Other" jurisdictions sometimes use cross-chargeability to reorder the calendar; the analysis is configuration-dependent.
EB-1 chargeable to mainland China has been retrogressed in recent visa bulletins, with a final-action date that has moved at a varying pace. The posture should be re-verified at the time of filing; the working assumption is that the China EB-1 priority date is not current and that the I-485 will not be filable concurrently with the I-140.
The I-140 itself is filed regardless of priority-date currency. Filing the I-140 establishes the priority date and is independent of when the I-485 or immigrant-visa interview becomes available.
Concurrent filing of I-140 and I-485 is available only when the priority date is current. For China EB-1 in retrogressed bulletins, the I-140 is filed first; the I-485 follows when the priority date becomes current.
Cross-chargeability under INA § 202(b)(2) [8 U.S.C. § 1152(b)(2)] is available where the principal and derivative spouse were born in different countries. A spouse born in Hong Kong, Taiwan, Singapore, Canada, the United Kingdom, or another "All Other" country can sometimes provide a faster calendar through cross-chargeability. Hong Kong and Taiwan are treated as separate chargeability areas from mainland China for visa-bulletin purposes.
A priority date from a prior approved I-140 in EB-2 or EB-3 can in some circumstances be retained for a later EB-1A filing under 8 C.F.R. § 204.5(e). Chinese-national petitioners with long-standing earlier priority dates often want this analysis run before the EB-1A is filed.
Premium processing is generally available for EB-1A I-140s, compressing the I-140 adjudication clock. It does not move the priority date or accelerate I-485 availability.
