Russian invasion of Ukraine

Seems to be a misunderstanding or purposeful misquoting.

What he web page says is:

Ukrainian nationals in Ukraine (who aren’t immediate family members of British nationals normally living in Ukraine, or where the British national is living in the UK), are currently unable to make visa applications to visit, work, study or join family in the UK through a VAC in Ukraine.

If you are able to safely travel, you can apply through a VAC in one of the nearby countries.

If you need assistance, contact UKVI:

Telephone: + 44 300 3032785 – select option 3 (0300 3032785 if you're in the UK – select option 3)
Monday to Friday 24 Hours
This is a free phone number, but network charges may still apply.

If you need to travel to the UK urgently

If you need to travel to the UK urgently for compassionate reasons you should apply for a visa in the usual way and include clear compelling or compassionate reasons for your visit in your application. You should also tell staff at the VAC about these reasons during your appointment.

Ukrainians in the UK

The Home Office has agreed some temporary concessions to support Ukrainian nationals currently in the UK who are now unable to return when their existing visa expires. These concessions will assist Ukrainian nationals in extending their stay in the UK without having to leave and re-apply from overseas.

If you’re in the UK and unable to return to Ukraine, you may be able to extend your visa or switch to another one even if your visa does not normally allow you to do so.
