India has dragged the US to the World Trade Organization's dispute settlement body over an increase in the professional visa fee.
Both sides will fight a separate case on India's ban on US poultry imports.
This is for the first time in the history of their bilateral relations that India is taking the US to the WTO.
In the 1990s, both countries were involved in a similar imbroglio concerning the US 'Super 301' legislation but the matter was resolved through bilateral discussions.
According to the dispute settlement norms, India has not yet made a formal complaint against the US in the DSB but has sought consultations with the US, which is the first step.
If both parties arrive at an amicable solution during the consultation process then the case would not be formally filed with the WTO.
"We have already made a request for consultation with the US over the issue of the hike in H-1B and L1 visa fees and discrimination against certain Indian IT companies.
We will inform them formally once the draft proposal is ready, which would be soon," a senior commerce department official told Business Standard.
In the complaint, India will cite the US's breach of commitment of mode 3 of services trade under the General Agreement on Trade in Services, Uruguay round of negotiations, which refers to the commercial presence of a country within the territory of another member-country with the objective of providing services.
India has said the US is using a particular law, Public Law 111-230 (Border Security Act), that substantially enhances fees in relation to applications for L1 and H-1B visas.
The bill nearly doubles the skilled-worker H-1B and L1 visa fees to as high as $4,500 per applicant (from around $2,320) for any company with at least 50 employees in which foreigners are more than 50 per cent
