I am currently on H1B visa and I have an I-140 approval for my EB2 green card application. In the future I am planning to apply for EB1A green card.

We have many EB-1A applicants who make their applications from outside the US and are successful. Being in the US is not required for such an application. Being employed in your field of expertise at the time of application is not a strict requirement, but is a factor. Emphasis in an EB-1A case is on whether the individual can prove that he or she is an alien of extraordinary ability.
