### EB1-C
**EB1-C** for function manager: [Chapter 4 - Multinational Executive or Manager | USCIS](https://www.uscis.gov/policy-manual/volume-6-part-f-chapter-4)
-   **Harsh call**: L1A is inter-company transfer - e.g. Dell Canada to Dell USA
        If you’re a manager category then you’ll be transferred on L1A
        Function Manager is if there’s only one person and important for the company, then you can qualify for function manager.
        You can define an important area and be a manager of that area or function.
        Behavioral attributes - working independently with little to no direction. High enough in the org to justify that you’re a manager.
        USCIS defines international employee as someone working in Dell XYZ outside USA for 1 year (excluding days you’re in USA for personal/work purposes)
        You need lawyers to say that you were performing as a manager outside USA and continue working as manager when in USA.
        L1A doesn’t need to go through labor verification cause you’re considered high enough. So your i140 is applied immediately in EB1.
        Tradeoffs: Have to stay with the firm, work permit is attached with the firm. Cannot change jobs.
        Convince manager that you’re going out of USA and come back in USA after a year. I want to do some research, want to talk to lawyers
