Do you already have a US nursing license? H4 visa does not permit one to work. Is your 3 years experience in a demand specialized area such as OR, critical care, emergency department, PICU, NICU, etc?
Aside from the fact that there is a high unemployment rate around the US (including new/inexperienced and experienced nurses coupled with many facilities not hiring new staff), there are very few facilities willing to go though the time and cost of recruiting and hiring a non-US PR/citizen internationally educated nurse.
Have you begun the process with the MA BoN (Massachusetts Board of Nursing) for obtaining an RN license by examination?
