8老師你好，我明天公民宣誓，宣誓完我是不是就拿到Naturalization/Citizenship Certificate？我要等到辦好護照才能給我媽媽申請綠卡？
根據這篇文章，http://bbs.wenxuecity.com/immigration/594792.html
我需要準備：
Sponsor Documents:
1. Copy of Naturalization/Citizenship Certificate.
2. Copy of the US passport.
3. Copy of sponsor’s birth certificate.
4. Financial documents, proof of income (last few salary stubs), last few tax returns, proof of employment (W2 forms), letter of employment, bank statements, savings, 401K certificate, and other documents demonstrating your financial strength.
必須要護照複印件嗎？那我是不是要先辦好護照呢？
謝謝8老師！
