Pros
Unreliable. Unprofessional. One Should not believe this consultancy.
Cons
This company offered me to sponsor H1B and took all the documents. I have trusted them to file the H1B petition. They told they will file my petition. However after the deadline of April first week, they ghosted me and ceased all contact. Because of this, I last offer from another reputed company. So do not trust them at all.
