Im here as a visitor (B-1/B-2 visa). Can I apply for a non-immigrant or immigrant work visa?
Yes. As long as your status in this country is legal, you may apply for a change of status to an appropriate non-immigrant work visa. All of the requirements must be met as described above, including an employer willing to sponsor you in an appropriate visa category. However,you are not permitted to enter the country as a visitor (B-1/B-2 visa) with the intention of obtaining employment. If you do receive a job offer while in the United States, you may apply for a change of status to a new non-immigrant work category. However, when you depart the U.S., you may have trouble obtaining a visa under your new status with which to re-enter the country. Please consult an attorney to discuss the appropriate ways to change your non-immigrant status. Application for immigrant work status is usually more time consuming. Please see question 12.
