Thanks for bringing this to our attention OP. We are grateful.
Here is the link for the survey
They are proposing to do it, but it is not finalised yet. I for one will not take part in it for a variety of reasons.
This people seem very desperate to make as much money from immigrant, to the extent of violating EU law, by charging fees which a British Citizen cannot be charged. It is outrageous.
I believe lots of people will be prepared to go for it, for job reasons and peace of mind, but why should it be , that richer people are able to get a quicker answer but poorer people don't. This changes might also result in all the staff being put on front desk, and less staff to process free application. This seems wrong.
Anyway i wish them all the best
