There are some curiosities and confusions here.
First the (my) confusions.
As far as I can see (and I think I've commented on this before, without ever getting it straight in my head) there are 3 types of fee:
• A notification fee of €250 (presumably usually paid by the player to FIDE)
• A transfer fee (designed to accelerate full eligibility to represent the new federation – presumably payable to FIDE)
• A compensation fee (payable from the new federation to the old federation in circumstances I’m not clear about).
I get the notification fee. That is, I understand it, I don’t get any money

.
The transfer fee depends on 3 things – whether the player has represented his/her old federation in a “FIDE event” (which can include continental junior tournaments, club competitions and so on) in the last 5 years, whether they are titled, and their length of residence in the new federation.
Taking John Dempsey as an example, he hasn’t represented SCO in the last 5 years so would be eligible for ISV in 12 months, sooner if he pays the transfer fee. Should I assume that the “length of residency” commences on his transfer date (i.e. is not the same as actual residency)? In other words, to be eligible for representative purposes in the first year of the waiting period higher payments apply (regardless of whether it is a one or two year waiting period). For the Spanish/Irish kids, it looks like €1500 is the cost of allowing them to participate in Croatia this year rather than next.
Does the compensation fee apply over and above the transfer fee? (I realise that it can be waived). Does this apply to all transfers, or only those where accelerated eligibility is sought? The rules refer to residence (which must make it awkward if the player is not actually resident in the new federation). Also, FIDE Rule B.04.6.4 seems to reset the two year clock to the last date of representation of the old federation (which is reasonable) but it states this in the context of the application (and regardless of whether the player was actually resident in the new federation at that time).
Having said that, I appear to understand the rules better than when I last looked – have they been rewritten?
Anyway, enough pedantry (if such a thing were possible

).
Going back to John, I see he must be in with a shout of going to the next Olympiad especially since Master Ghazarian has no sooner switched from USA to ISV than he’s switched back again. Good luck to John, but his citizenship is classified as “ENG”. I know there are several classes of UK Citizenship but English is not one of them AFAIK. Perhaps “UK” as applied to GM Davies would be more appropriate.
I note (without further comment) that Phil Thomas has become “ENG”
The Greek lad has been in Edinburgh for a few years – presumably a Scot moving to the Edinburgh of the South may not be due the notification fee to change federations as there would be a fair chance that they hadn’t played any FIDE rated games in the first place…
