Prime Minister Manmohan Singh arrived on Sunday in Washington for a four day US visit as the state guest of US President Barack Obama.
Manmohan Singh was accorded a ceremonial welcome at St Andrews Air Force Base.
Manmohan Singh will hold talks with Obama on Tuesday and will raise the issue of the misuse of aid to Pakistan and the threat of WMDs falling into the hands of terrorists.
"We will raise the issue of diversion of US aid to Pakistan for boosting anti-India terror infrastructure," sources said.
"Threat of WMDs falling into the hands of terrorists is a serious one and this issue will also be raised," sources added.
Besides firming up a framework for counter-terror cooperation and completing remaining steps of the nuclear deal, the two sides are expected to ink 10 agreements in areas ranging from intellectual property rights, trade and investment, agriculture, health and green technologies.
