Hi, I am new to this site. Here's the situation: I am petitioned by my parents (lawful permanent resident) and was already approved. I am the eldest in the family and by the time the petition was filed I am already above 21 years old. While my sibling were below 21. There were no problems to my siblings except for myself.. I had I-130 case and my priority date is 2001. I am confuse in which preferences I will fall? I am still unmarried

4. INA Section 203(e) provides that family-sponsored and employment-based preference visas be issued to eligible immigrants in the order in which a petition in behalf of each has been filed. Section 203(d) provides that spouses and children of preference immigrants are entitled to the same status, and the same order of consideration, if accompanying or following to join the principal. The visa prorating provisions of Section 202(e) apply to allocations for a foreign state or dependent area when visa demand exceeds the per-country limit. These provisions apply at present to the following oversubscribed chargeability areas: CHINA-mainland born, INDIA, MEXICO, and PHILIPPINES.
