现状：BS, PhD candidate only, no master degree, but have 6 year research experience after BS graduation in 2000. Want to try NIW now if possible.
疑问：the 6-year research included 2 main fields (#1 3+yr and #2 2+yr), which are related but not exactly the same, and the second field is much closer to national interests. Question is: can the 2 fields experience combined to be counted as more-than-5yr experience and qualified as NIW applicator?
