The twenty-four-year-old could appear for the home nation at Pyeongchang 2018 with reports suggesting in June that South Korea had offered her a passport.

Luge is not a sport in which the Koreans traditionally excel, although they will be keen to put in a strong showing in all events at their home Games.

Germany, on the other hand, has produced a long line of luge talent with Frisch now appearing for South Korea during testing of the Alpensia Sliding Centre, which is being built for the Pyeongchang Olympics.

Competing for Germany, Frisch won gold medals at the Junior World and Junior European Championships, and claimed the overall Junior World Cup title in 2012.

She retired from the sport when she failed to make the senior Germany squad for the 2015-16 season, but now may be set for an international comeback.

The International Luge Federation said, however, that no official license application from South Korea had been received for Frisch.

In June it was reported that the Korean Olympic Committee (KOC) believe they can challenge for a medal with Frisch on board.

"In her 15 years of luge career, she has shown stable performances in almost all tracks in the world," the KOC said in a statement to Yonhap.

"If she joins the national team, South Korea can not only expect a medal in women's singles, but also can expect good influence in the team relay event which is composed of women's singles, men's singles and doubles."

Fast-tracking the citizenship of foreign athletes is not a new phenomenon in sport but it is certainly a controversial one with many believing it is not in the correct spirit.

In April it was reported that Canadian ice hockey players Matt Dalton and Eric Regan had been given Korean citizenship in order to play for the national team in Pyeongchang, while passports were also issued to Russian biathletes Anna Frolina and Alexander Starodubets.

South Korea already boasts homegrown pedigree in the other sliding sports, with skeleton's Yun Sung-bin finishing second in the 2015-16 World Cup standings.

In bobsleigh, Won Yun-jong and Seo Young-woo went one better, winning the two-man competition. 

Testing at Alpensia will be key for Pyeongchang organisers, with safety issues highlighted during an International Olympic Committee (IOC) Coordination Commission visit this month.

The course was hit by problems in March when testing was cut short as there was not enough ice on the upper section.
