Suu Kyi and 20 other members made the submission in the capital, Naypyitaw, 350 kilometres north of Rangoon, a spokesman for the NLD said.
The international community has welcomed the NLD's decision as an important gesture of rapprochement between the government and the opposition party, which boycotted the November 7 polls last year.
NLD's application to return to the political fray came days before the arrival of US Secretary of State Hillary Rodham Clinton, scheduled to visit Burma Wednesday through December 2.//DPA
