we have claimed land near Kielce and properties in Sosnowiec, have passports, but so far nothing??
This deadline is for eastern pre war Poland, "Kresy"now Ukraine. Poland reports having many more claims than they expected. They are revieewing and as long as you reach the deadline (that may be extended) you will be all set. IMO this may be reimbursed by Russia in the future as requested by EU and this is still in the air. Contact me by email if you need the forms.
