Hi Mark,
I went to Phil Embassy today and i saw the announcement that British Consulate in Tel aviv is closed for student and working visa application.
If your girlfriend is more than 4 years here and she was released in her work or her employer died. She is not entitled to get a legal working permit anymore meaning she cant able to pursue Visitor Visa application.
The only chance to bring her is using Fiancee or Spouse Visa.
Where is her work? Just be patient and everything will be alright
