If you get a green card, how do you plan to continue working in the United States?

You need to outline a vision for the immigration officer hearing this case, that is, if you get a green card and come to the United States, how to use the "outstanding ability" you advocated in your application to continue working in the same field and bring benefits to the United States. This is an expectation for the future, but it should be based on credibility and feasibility, not empty promises. It is certainly better to have conclusive evidence, such as employment letter, market research report, business contract, investment letter of intent, proof of funds, etc. , not just "the plan to come to the United States."
