• 可以，你有H1B工签（and其他美国工作签证）或者EAD工卡就行。

    毕竟没有绿卡不代表不可以合法工作，拥有H1B工作签证或者其他劳工签证，EAD工卡都（就业授权文件）可以留在美国工作。

    先讲讲最常见的H1B工作签证吧，H1B工作签证是在美国短期工作的人士所发的临时工作签证。H1B工作签证持有人首期工作期限是三年，可以延期一次至六年。如果这期间雇主正在帮助其申请绿卡，则可以不限次数地延长，每次延期一年，直到拿到绿卡。不过不管是H1B还是其他美国工作签证，首先都需要雇主帮助向美国移民局申请，获批后再持批准书等资料到美国驻中国领事馆申请签证。

    Yes, you can—provided you hold an H1B work visa (or another type of U.S. work visa) or an EAD card.

    After all, not possessing a Green Card does not preclude you from working legally; holding an H1B work visa, another type of employment-based visa, or an EAD (Employment Authorization Document) allows you to remain in the United States and work.

    Let’s start with the most common type: the H1B work visa. The H1B is a temporary work visa issued to individuals intending to work in the United States for a limited period. The initial validity period for an H1B holder is three years, and it can be extended once, up to a maximum of six years. If, during this period, the employer is sponsoring the employee for a Green Card, the visa may be extended indefinitely—typically in one-year increments—until the Green Card is obtained. However, whether applying for an H1B or any other U.S. work visa, the process invariably begins with the employer filing a petition on your behalf with U.S. Citizenship and Immigration Services (USCIS). Once that petition is approved, you must then take the approval notice and other required documents to a U.S. consulate in China to apply for the actual visa stamp.

    所以办理工作签证，最重要的是满足以下的条件：

    1、找到美国的工作，有工作合同；2取得美国公司的签证担保。

    此外，以下是美国不同的工作签证分类，适用于不同工作情况：

    H-1B签证：

    这是最常见的专业工人签证，适用于在特定专业领域有专业资格的外国工人，通常需要美国雇主的支持和赞助。

    PH-2B签证：

    适用于非农业临时工人，如季节性工人、娱乐行业工人等。

    H-2A签证：

    适用于短期农业工作者

    L-1签证：

    适用于跨国公司的内部调派员工，包括经理、高级职员和专业员工。

    中0-1签证：

    适用于具有杰出能力的外国人，如诺贝尔奖获得者、国际知名艺术家、运动员等 。

    中J-1签证：

    适用于交换访问学者，包括学术、职业、研究和其他类别。

    PF-1签证：

    虽然是学生签证，但学生可以在学习期间申请工作许可（如CPT或OPT），以获得实际工作经验。

    Therefore, the most critical requirements for obtaining a work visa are as follows:

    1. Secure a job in the United States and possess an employment contract; and 2. Obtain visa sponsorship from a U.S. company.

    Furthermore, listed below are the various U.S. work visa classifications, each tailored to different employment scenarios:

    H-1B Visa:

    This is the most common visa for skilled professionals, applicable to foreign workers possessing specialized qualifications in specific professional fields; it typically requires the support and sponsorship of a U.S. employer.

    H-2B Visa:

    Applicable to temporary non-agricultural workers, such as seasonal workers, workers in the entertainment industry, etc.

    H-2A Visa:

    Applicable to short-term agricultural workers.

    L-1 Visa:

    Applicable to employees of multinational corporations who are being transferred internally, including managers, executives, and specialized staff.

    O-1 Visa:

    Applicable to foreign nationals with extraordinary abilities—such as Nobel Prize laureates, internationally renowned artists, athletes, etc.

    J-1 Visa:

    Applicable to exchange visitors, encompassing categories such as academics, professionals, researchers, and others.

    F-1 Visa:

    Although primarily a student visa, it allows students to apply for work authorization (such as CPT or OPT) during their studies to gain practical work experience.

    还有一种情况就是EAD工卡（就业授权文件）：

    EAD是提供给那些因其特定的移民状态或情况而被授权在美国工作的人的文件。它允许持有者在美进行就业，而无需具体的雇主赞助。EAD通常需要通过提交1-765表格申请，并根据个人情况可能需要支付申请费用。

    EAD对于那些拥有非移民身份但不允许自动工作的人来说尤其重要，例如某些F-1或M-1学生。EAD的有效期限通常较短，且与申请人的特定情况或身份有效期相匹配。持EAD的人必须在其到期前申请续期，以避免工作授权中断。

    但是不同的是比起美国工签和工卡，美国绿卡的可居留时间会长，可以做想做的工作，随时换，住满五年还可以申请做美国公民。而其它工作签证的只能在发签证的公司工作，如果要换工作还要先确定新雇主是否会帮你申请签证，比起绿卡来说要更不方便一些。

    Another scenario involves the EAD (Employment Authorization Document):

    An EAD is a document issued to individuals authorized to work in the United States based on their specific immigration status or circumstances. It permits the holder to engage in employment within the U.S. without requiring specific employer sponsorship. Obtaining an EAD typically involves filing Form I-765, and—depending on the individual's specific situation—an application fee may be required.

    EADs are particularly important for individuals holding non-immigrant statuses that do not automatically confer work authorization—such as certain F-1 or M-1 students. The validity period of an EAD is typically limited and is aligned with the duration of the applicant's specific status or circumstances. EAD holders must apply for a renewal prior to the document's expiration to avoid any interruption in their work authorization.

    However, a key distinction between a U.S. Green Card and other U.S. work visas or EADs lies in the duration of residency and employment flexibility. A Green Card grants long-term residency rights, allows the holder to pursue any desired line of work—with the freedom to change jobs at any time—and, after five years of residency, enables them to apply for U.S. citizenship. In contrast, holders of other work visas are generally restricted to working for the specific employer that sponsored their visa; if they wish to change jobs, they must first verify whether the prospective new employer is willing to sponsor a new visa application—a process that is considerably less convenient compared to holding a Green Card.

    L1eduZ">工作许可不一定是绿卡，美国身份有问题，还是可以申请工卡的，正常报税。有工卡，公司就可以正常招聘。

    还有就是工作签证，也是合法的。高端的L1 ,中端的h1b,低端的EB3 EW3这种。

    旅游来美国，没有身份的，洛杉矶和纽约做保姆清洁15～25时薪我觉得是一定可以找到工作的。大概几个月可能就可以申请到工卡了吧。

    找工作的话，我觉得洛杉矶纽约不一定好找，非法移民太多，太卷。可以看看休斯顿，芝加哥这些地方。

    出力的工作，一个月5000左右难度不大。行政文职我觉得就3000左右吧。带点技术的蓝领，8000以上。考电工，水管工都有中文的培训学校。

    A work permit is not necessarily the same thing as a Green Card. Even if there are issues with your immigration status in the U.S., you may still be eligible to apply for a work permit (EAD) and file taxes normally. Once you possess a work permit, companies can legally hire you.

    Another avenue is the work visa system, which also provides legal status. These range from high-tier options like the L-1 visa to mid-tier options like the H-1B, and lower-tier categories such as the EB-3 (EW-3).

    If you have traveled to the U.S. on a tourist visa and currently lack formal immigration status, I am confident that you can still find work—specifically as a nanny or cleaner—in cities like Los Angeles or New York, earning an hourly wage of $15 to $25. It typically takes just a few months to successfully obtain a work permit.

    However, when it comes to job hunting in general, I don't necessarily think Los Angeles or New York are the easiest places to find employment; the competition is intense due to the high volume of undocumented immigrants. You might want to consider looking into other locations, such as Houston or Chicago.

    For physically demanding jobs, earning around $5,000 a month is not difficult to achieve. Administrative or clerical positions, on the other hand, typically pay around $3,000. For skilled blue-collar trades—those requiring technical expertise—earnings can exceed $8,000. Furthermore, there are training schools available (including those offering instruction in Chinese) to help you prepare for licensing exams to become an electrician or plumber.
