How can I keep my IR currency outside the USA? I am an FAA PPL/IR holder living in Spain.

My IR license was issued in May 13 of 2016, it has been over 6 months so now I need to log my 6HIT with a safety pilot.

Is it possible to complete the currency requirements in a simulator even though I have gone past the 6 month mark without flying? Is it possible to complete the currency requirements in the EU with an instructor?

Thanks for any help, my flight school is being really unhelpful as they seem to actually know far less than I do about FAA regulations, this is my last hope!
The easiest option is to find a US CFI/AI holder in the country you are in, to sign off on your approaches.  It might be allot easier if s/he is also a Spanish CFI particularly if you are flying in a Spanish registered aircraft.  You do not indicate if you hold a certificate from Spain.

It is not uncommon to find instructors with US FAA CFI ratings in other countries.

There is no prohibition of a US CFI giving instruction in another country.  There may be of a given country, or operational limitations imposed by aircraft registration, host country operating rules, and insurance limitations, as well as owner / lease limitations.  

However, I routinely sign off US pilots for approaches made at Canadian airports, in fulfillment of their US instrument recency requirements.
