How to define your FIELD in NIW?

[nist]

I have a technical question regarding NIW:

Are there any regulations on how to define your FIELD? For example, if you are a biologist working on mosquito control, how should you state what your field is? Biology, or mosquito control? The choice would make a huge difference when you argue your impact on the field.

Apparently, the narrower the field, the easier to argue your impact. But how narrow can it be? If there¡¯s no limitation, then you can narrow it down so that only you fit the field (such as mosquito control against xx virus), and you will be the most important and influential scientist in the field. Will the BCIS buy it?

Thanks.

Remember if you change job, the wider field the better.

Are there any regulations then? Does the wording of the field have to match the 'non technical job description' in form I-140, or is if flexible? When you change job, will the 'title' in 140 determine your field, or will the 'non technical job description' do? Thanks.
