US Embassy: Apply for visa 90 days prior to employment start date

The United States (US) Embassy here on Thursday asked visa applicants to apply up to 90 days before their employment begins.

"Applying for your work #USvisa? You can apply up to 90 days before the employment start date noted on your I-797 form," the US Embassy wrote in a tweet.

The I-797 form is a document the United States Citizenship and Immigration Services (USCIS) uses "to communicate with applicants/petitioners or convey an immigration benefit," reads the USCIS website.

The US work visa for Indian nationals is one of the most important issues between US and India bilateral ties.

H-1B is considered as the most sought-after work visa among highly-skilled Indian professionals. It is a non-immigrant visa that allows US companies to employ foreign workers in specialty occupations that require theoretical or technical expertise.
