Quoting: steve d
My friend was at the Consulate yesterday applying himself. They said it will be ready in ten days, but he went for the most expensive option ( about PLN 700 )
He asked if it must be a UK citizen who must validate the photo, a Polish student validated his and it has been accepted.
Hope this helps
looks like you are correct see below notes from passport application:
Note 8 – Section 10 – Countersignature
When you have completed the form, someone who has
known you personally for at least two years should complete
and sign Section 10. That person should be a British citizen,
other British national or Commonwealth citizen who is a
Member of Parliament, Justice of the Peace, Minister of
Religion, Bank Officer, Established Civil Servant, or
professionally qualified person, e.g. Lawyer, Engineer,
Doctor, School Teacher, Police Officer or a person of
similar standing. Procedures include a check on the
authenticity of countersignatories.
If you do not know a British national or other Commonwealth
citizen locally with these qualifications, a citizen of the
country in which you are residing may complete and sign the
form, provided he/she has a similar standing in that country
has known you for two years and the Consul considers
his/her signature to be acceptable. A member of your family
should not countersign. (See also Note 10,
‘Photographs’). In certain cases you may be asked to
produce further documentary evidence of identity.
