H4 to H1 issue

[sulo]

I am currently living on a H4 visa since Aug 2011. I am seeking a job in the US.I have a training in Architecture (B.Arch) graduated 2008, and a masters in Urban Design & Planning (MAUD) graduated 2010. I came across various short term courses for BA & QA online. Since I was finding it hard to find a job in my profession, I plan to take up courses in another field (BA/QA) and try for job. Will that affect my H1B application as i do not have a background education in that field? Will I be able to apply for a job as a BA with some training in that field and get an H1B? Suggestions please, thank you.
