The white paper states that the government will "introduce a new English language requirement for all adult dependants of workers and students at level A1" under the Common European Framework of Reference for Languages (CEFR). Some observers think this may include family members of GBM visa holders. This has been a frequent question at seminars about the white paper for foreign companies, but expert views on the matter are divided. The U.K. Home Office has not clarified whether this is the case, and told Nikkei only that "further details will be available in due course." While the required level of fluency is not that high, there are concerns about the time and effort needed to take the test. In Japan, the Eiken grade 3 test, which is equivalent to the CEFR A1, costs 5,000 yen ($35) or more, depending on the venue.
