The offer was made during a phone call by US Secretary of State John Kerry to Nigerian President Goodluck Jonathan.
"Jonathan welcomed Kerry's offer to send a team to Nigeria to discuss how the United States can best support Nigeria in its response," White House Press Secretary Jay Carney told reporters at his daily news conference.
In addition, the US Embassy in Abuja is prepared to form a coordination cell, an interdisciplinary team that could provide expertise on intelligence, investigations and hostage negotiations, help facilitate information sharing and provide victim assistance, he said.
The outlawed militant group Boko Haram claimed responsibility earlier for the April 14 abduction of some 276 teenage girls from their boarding school in northeastern Borno state.

US President Barack Obama, he said, has directed that Kerry and the Department of State do everything they can to help the Nigerian government find and free these young women.
Responding to question at a different briefing, State Department spokesperson Jen Psaki said the nature of assistance is still being determined.
Psaki said before this offer that Kerry made this morning to Jonathan, the US had had already taken a number of steps, given that Boko Haram is a designated terrorist organisation and one that the US have had increasing concerns about.
