> H1B visas are issued to more than software engineers

Not really. More than 70% of all H1Bs are going to software positions. Biomedical engineers are less than 1%, so a rounding error

> you probably want to provide a source for that number

Just google it yourself.

If you are referring to the statistics for "computer-related" positions and trying to equal "computer-related" to "software engineers", I have nothing to say other than you are just trying to push your agenda.
