Devyani Khobragade, Outraged Indian MPs have spoken out in parliament against the arrest and alleged ill-treatment of one of its diplomats in New York last week.
Upper house opposition leader Arun Jaitley said her arrest was a clear violation of the Vienna convention.
Devyani Khobragade, deputy consul general, was handcuffed upon arrest and later strip-searched.
She denies visa fraud and making false statements over allegations that she underpaid her Indian maid.
The maid had complained the diplomat was paying her less than the minimum stipulated wages under US visa requirements.
Following her arrest, Ms Khobragade appeared in court last Friday and was freed on bail.
