FGS' Wooden Fish program is the only one I know of that seems to fit the description that you give above. However, it may be a tad late to register- you can contact Ven. Hui Feng here on the forum for more information.
It might also be worth contacting the other large Taiwanese Buddhist organizations, such as Dharma Drum Mountain and Chung Tai Chan, for more information. Ven. Indrajala, who also posts here, is familiar with DDM , having served there as a translator for an extended period.
Hope this is of at least some assistance.
The Woodenfish HBMLP is no longer based in Taiwan. The one I'm presently running is the Fo Guang Buddhist Monastic Retreat. However, application dates for this year are already past. The main question is: Can the participant speak Chinese (Mandarin)?
If so, there are a large number of programs all over Taiwan, just take your pick. If not, and one requires English, then the FGBMR may be one of the few programs available.
