回复：没听说过这种事，你知道拒绝的理由了吗？

The letter is:

It is your contention that you qualify as the derivative spouse or child under section 203(d) of the Act. Service records indicate that the application for adjustment of status filed by the principal applicant was denied or withdrawn.
The evidence of record does not estabish that you qualify as the derivative of another adjustment applicant or of a person granted permanent residence.

Therefore, your application is denied.
The regulations do not provide for an appeal from this decision.
