申请 E-2 投资者签证需要满足哪些条件？
一般而言，申请人必须是与美国签订 E-2 条约国家（treaty country）的公民，在一家真实且正在运营的美国企业（real and operating U.S. business）中投入相当规模的资金，并对投资资金和企业拥有控制权。投资资金必须处于风险之中（at risk），且相对于企业的设立或收购成本而言具有实质性（substantial）。同时，企业不能属于边际性企业（marginal enterprise）。申请人还必须赴美负责企业的开发和管理（develop and direct the enterprise），通常需要拥有至少 50% 的企业所有权，或通过其他方式对企业拥有实际运营控制权。
E-2 身份并不仅限于投资者本人。某些条约投资者或符合条件企业的员工，如果将担任高管或管理职位，或具备对企业运营不可或缺的特殊技能和资质，也可能符合 E-2 资格。此类员工通常必须与条约投资者或符合条件的雇主具有相同国籍。
E-2 持有人的配偶及未满 21 周岁的未婚子女可以随同申请或随后赴美，其国籍无需与 E-2 主申请人一致。持有有效 E-2 身份的配偶因其身份本身即享有工作授权（employment authorized incident to status），通常无需单独申请就业授权文件（EAD）；载明 E-2S 身份类别且仍在有效期内的 I-94 通常可作为工作授权证明。
E-2 属于非移民签证类别（nonimmigrant classification）。只要持续满足相关要求，E-2 身份通常可以续签；但 E-2 本身并不直接提供获得美国永久居民身份（绿卡）的途径。

It depends on whether you are applying as a principal applicant or as a dependent.
As an E-2 principal applicant, you must hold the nationality of an eligible treaty country. Mainland China is not an E-2 treaty country, so mainland Chinese nationality alone does not meet this requirement. If you hold a qualifying treaty-country nationality, you may be eligible, subject to the other E-2 requirements.
As a dependent, you do not need treaty-country nationality. A mainland Chinese citizen may qualify for an E-2 dependent visa as the spouse or unmarried child under 21 of a qualifying E-2 principal applicant.
If neither route applies, other visa categories may be available depending on your circumstances.
Yes — your spouse and unmarried children under 21 may apply for E-2 dependent visas to accompany you or join you later. They do not need to hold treaty-country nationality.
Your spouse may generally work in the United States while maintaining valid E-2 dependent spouse status, without obtaining a separate employment authorization document. An unexpired I-94 showing E-2S status serves as evidence of employment authorization. Your spouse and children may study, but children cannot work based on E-2 dependent status.
| Spouse | Unmarried children under 21 | |
|---|---|---|
| Work | Yes, incident to status (no separate EAD) | No |
| Study | Yes | Yes |
