Plan to work in US for good

Good day! Anyone here could tell me good advise/approach to migrate to U.S.?

HERE is the situation: I have gf and she has tita and tito living in US (already US citizens)

So far in what I have researched to migrate are the following:

  1. Student Visa (F1)
  2. Working Visa (H1-B)
  3. Marry a U.S. Citizen
  4. Nursing/Medical field

About us: Engineers (3yrs experience) We are planning to apply for work related to our profession. Is there any possible route for us to work there?

Also, we know na mataas proseso ng H1B visa, can the employer still hire me and provide temporary visa while H1B visa is being processed? Or any suggestions to possibly work in US.
