## 解决方案

1. ```
   Ensure all business activities are limited to permissible categories: attend meetings, conferences, negotiate contracts, or consult. Do not perform any productive work (e.g., coding, writing, accounting) for a US employer. Keep documentation of purpose and duration.
   ```
2. ```
   If you must work for a US company, apply for a proper work visa (e.g., H-1B, L-1, O-1) before entering the US. Do not enter on B-1/B-2 with intent to work.
   ```
3. ```
   For short-term assignments, consider the Visa Waiver Program (ESTA) if eligible, but same work restrictions apply. Alternatively, use a B-1 in lieu of H-1B for very limited scenarios (e.g., installing equipment under contract).
   ```

## 无效尝试

- **** — Assuming that remote work for a foreign employer is allowed under B-1/B-2; USCIS considers any work performed while physically in the US as US employment if it benefits a US entity. (65% 失败率)
- **** — Believing that volunteering for a US company is permissible; unpaid work that displaces a US worker is still prohibited. (50% 失败率)
- **** — Thinking that a B-1 visa can be converted to H-1B status while staying in the US; change of status is possible but requires strict conditions and is not automatic. (70% 失败率)
