I am as confused as what due to people at my office informing me of conflicting stories

My single entry non immigrant visa B is about to expire at the end of the month. Although my work permit has been applied for, it wont be ready by then.

Well do I need to leave the country and apply for the visa once this once finished, or as someone said, can I extend it for 30 days at HKT immigration office until my work permit finishes and then go outside the country and apply for a mulitple entry non imm visa B

You can go to Immigration and they'll extend you to accommodate the work permit decision.

Dr. how about the situation after the WP is granted?

In my case got confirmed by immigration for 1 year and subsequently WP for 1 year. Understand some people first receive visa and WP for 3 or 6 months.

In any case, no need to leave the country to apply for a new visa once the WP is clear. WP follows always the visa.

If one whishes to leave the country apply for a re-entry permit.

It is always difficult, but Immigration can give an extension to the original visa once the work permit issues, but only if they feel happy on the day.
