I don't know how old you are, but if you can't read English, find somebody to translate it for you.
Your question is not clear. Let me assume your mother is now in USA and you are in China. In March this year, she submitted 2 applications. Why 2? She can submit a refugee claim for herself, but nobody else. She can't submit a refugee claim for you. You are confusing everyone.
Let me assume she submitted her refugee claim in March this year. She should have by now received her first hearing and submitted her support document. It may take her many years before receiving a confirmed status. Some refugee claimants have been living in USA for 10 years, without any status in light. USA government is detaining thousands of refugee claimants in jail, including about 5000 under 18 years of age.
Does your mother have a chance? Currently, there are 2 acceptable claims: (the first one I can't say otherwise, I will be blocked) and one child policy. I don't understand since you can write in Baidu, you must not be a very small child. Your mother may have passed her active child rearing age, and if so, her ground is shaky.
If she is successful, you are also eligible for a refugee claim if you continue to remain as a minor. I would doubt it by the time you are still a dependent when she is successful. You eligibibility for the claim does not mean you will become a convention refugee. You have to go through the same process like she did. If you are a male, your chance is slim, since the one child policy does not affect you.
Overall, I would say:
1. you are not a refugee claimant at this time.
2. think about it. If the USA government issues a convention refugee status to you in China, would the Chinese government give you a passport to leve? No way.
3. Your mother must have submitted all support documents and her affidavit; otherwise she might have abandoned her claim.
4. Your mother should have attended the first hearing. She may have to wait for a few years before the next hearing to come.
5. If she fails to attend any hearing, there will be a deportation order issued on her.
6. If she changes her address, she must notify the government.
The above is based on an assumption you are in China. This is another ball game if you are in USA.
Good luck.
