Can a surpised creature fall prone voluntarily on their turn?

In my answer to a related question I said that a surprised creature cannot be commanded (Command spell) to grovel as it requires using their move action to fall prone. L0neGamer pointed out that that isn’t actually what the rule says.

The relevant text from Being Prone under Movement and Position states:

You can drop prone without using any of your speed.

Clearly this means that any effect which drops your speed to 0 does not prevent you from dropping prone. This is not what the surprised condition does:

If you’re surprised, you can’t move

I don’t believe that move is the same thing as speed. If my speed is 0 I can still drop prone, draw a weapon or take other free object interactions as part of my move. If I can’t move I can’t do any of these things.

Can a surprised creature drop prone voluntarily on their turn?

After voluntarily left Uk , will I get visa to go back again? [on hold]

I had live Uk almost 8 and half years . I had overstayed there like 7 years . Firstly my visa was granted to uk and I went to uk as dependent visa from my country . And after that I just stayed illegally there without re applying again because I didn’t have any kind of way to apply . So I overstated there . And currently my husband now is French national .And we decided to go back to my own country with voluntarily departure . And I paid all my expenses all by my self . And went back to my country where me and my now husband got married there. And after 5 months I applied to France visa . And i got the visa again to go to France with my husband . And now I am in France and I have a resident permit here now . And my husband and I am planning to go to Uk to settle there together as I will be applying for EEA family permit visa . And I know it’s been 1 year that I have left Uk . So I am eligible to apply . But still I am nervous to apply . And I checked the form as well . In there I have give the information about my last 10 years travel history as well . As I will write what the truth is . But still i am getting nervous . Please could you reply me back ? Would you think I will get visa in my situation? Please reply me back thank you very much

Can creatures with Spell Resistance voluntarily fail saving throws?

Pathfinder’s magic rules say that a creature with “special resistance to magic” can voluntarily fail a saving throw against a spell.

Voluntarily Giving up a Saving Throw

A creature can voluntarily forego a saving throw and willingly accept a spell’s result. Even a character with a special resistance to magic can suppress this quality.

But the rules for spell resistance seem to imply the opposite, that a creature would need to drop its spell resistance before being affected by the spell.

A creature can voluntarily lower its spell resistance. Doing so is a standard action that does not provoke an attack of opportunity. Once a creature lowers its resistance, it remains down until the creature’s next turn. At the beginning of the creature’s next turn, the creature’s spell resistance automatically returns unless the creature intentionally keeps it down (also a standard action that does not provoke an attack of opportunity).

I’m confused how these rules interact. If a creature with SR hasn’t lowered their SR, can they voluntarily fail the save without a caster level check from the caster? Or does “special resistance to magic” refer to something other than SR?
