It's quite hard to get work visa for single ladies these days unless your employer is one of the Q companies.

Our company tried to hire single ladies for office administration jobs but found it hard to get a work visa for them. Finally settled on hiring husband sponsored ladies.

I also heard some single lady teacher assistants in some private schools unfortunately were let go because of the same situation and had to be replaced also with ladies with husband-sponsored visas.

But you can try your luck.
