You have to know where you'll physically be, to get the validation.
Besides, you said you did it before. There's no CPL to CPL validation anyway.
So unless you mean it in terms of IR privileges, why not just use your PPL validation?
Unless the licence numbers etc changed, meaning you have to redo it.
There's no advantage of having IR added to validation unless you actually want to exercise those rights without doing the FAA IR checkride. If you're relocating to USA, then you still have to do the few hours before checkride at least and the checkride for IR. It'd be only good to do the validation if you were shooting for ATP. Not your case.
On a side note. Your mention of 'recently', you mean the DV-2013 results of which are available past 7 days? If you have very high (over 20 000) case number, you may not be able to sort the paperwork before deadline. Over 30k, you may as well forget it. You'd also need someone to provide the affidavit of support, US based individual/company.
