Under the various employment based categories, Category I based permanent residency is the most difficult to obtain. Initially, the foreign national must determine if he/she is eligible for lawful permanent residency according to the USCIS guidelines.
An applicant filing an EB1 alien of extraordinary ability application may self-petition, but an applicant filing under outstanding researcher and/or professor and multinational manager must have a sponsoring employer.
One of the ways a foreign national (alien) can become a permanent resident is through a permanent employment opportunity in the United States. There are five employment-based preference categories.

A temporary worker visa is a nonimmigrant visa for individuals who wish to work temporarily in the United States. There are several categories ("classifications") of temporary worker visas. Some of these classifications have annual limits. The applicant’s qualifications, type of work to be performed, and other factors determine what type of visa is required under U.S. immigration law.
Below is a summary of these visas. For more information on any of them, click on the visa title or on the menu to the left.
Got GC in 18months (RIR Labor application to 485 approval). Rajiv Khanna (RK) helped me out of a mess that I thought was impossible to solve. He helped out an unknown emailer, spent hours analyzing the situation over the phone and devised a game-plan. Guess what, without signing a retainer or expecting compensation. I still remember when I called other “big lawyer” for help, first thing her office wanted was my credit card.
Story began in summer of 2003. When I found out that my earlier lawyer had screwed up the whole 140/485 application and was eventually denied, loss of 4years of waiting. I then emailed RK for help. He patiently heard the story and advised that I should redo the whole application from point A. Even though dread of going through whole labor application all over again was overwhelming, RK was absolutely correct that earlier labor was approved under incorrect language, mistakes many inexperienced lawyers make.
Best thing is that he sticks by the books, remains honest about the situation and never promises miracles. Apart from RK’s excellent competency and vast experience, he has excellent well-trained support team. That really makes a huge difference because game-plan is one thing, while organizational support & efficient execution is other.
