我们正在准备NVC亲属移民材料， （follow up, spouse). 有一疑问， 请指教
1。 photocopies of supporting documents, 需要提供petitioner 和beneficiary 的材料, 还是任何一方？
2。 photocopies of supporting documents 里的petitioner documents 指的是什末？
注： photocopies of supporting documents list following: adoption documents, birth certificates, court and prison records, marriage certificates, military records, petitioner documents, passport, police certificates.
万分感谢
