Iam A Chef I Have B1/b2 Visa I Can Apply For Green Card

How can someone with a B1/B2 visa get a US green card?

It is theoretically possible to adjust status from B-1/B-2 to permanent resident, if you are admissible as a PR, but in practice this almost never works.When you apply for a B-1/B-2 visa, and again when you enter the country, you are asserting that you are not entering with the intention to immigrate to the United States. If you then, shortly thereafter, attempt to adjust status to an immigrant status, USCIS will conclude that you were foresworn on your original B-1/B-2 visa application and that you really intended to immigrate all along. They will thus revoke your visitor's visa, and use your false declaration to justify denying your adjustment of status as well. This applies to most of the immigrant visa classes.There are a few exceptions to this. For example, if you have a pending petition in the diversity lottery and you are notified while you are in the United States on a visitor's visa that you've won the diversity lottery, you can apply to adjust status without leaving the United States and without violating the "no immigrant intent" rule. There is a guideline that having an outstanding application in the diversity lottery does not demonstrate proven immigrant intent, because the chances of actually winning the lottery are fairly low. The same applies if you have a pending noncurrent petition for a green card in an oversubscribed priority class that is unlikely to be granted soon. If, for some reason, such a petition is rapidly advanced and becomes current while you are in the country in a visitor status, you can apply for adjustment of status on the basis of that petition. This would, however, be an exceptional situation. In both such cases, the petition would have had to have been filed before applying for the visitor visa.Also, if you've been in the United States more than three months and your basis for applying is because you plan to marry, or have already married, a US citizen and you can convince USCIS that you didn't have plans to get married when you entered the country, you might be able to adjust status to a fiancee visa or conditional LPR (spouse of citizen). Might. Don't count on it.The other exception is that you can apply for asylum while present on a B-1 or B-2 visa, if you've been in the United States for less than a year. A grant of asylum status will lead to the opportunity to apply for permanent residence after one year.

If I enter the US with a B1/B2 visa, is there a way for me to change it to a permanent residence status?

This is a very interesting question - one that I am certain many viewers have in their mind. Of course, entering on a visitors visa means that when you obtained that visa and upon entering the United States your 'intent' was non-immigrant - that is, your intent was and is to return home after your temporary stay; you've also agreed to abide by your visa's specific limitations and requirements. For example, B-1/B-2 status does not allow employment. That said, in the real world it is fully understood in the law that entrants after they have been here for awhile may have a change of mind about their stay. Sometimes people want to extend the status for a few more months, they decide they want to change their visa so they can attend school full-time, or occasionally visitors meet and fall in love and want to remain after marriage. To answer your question specifically, extending or switching to a new non-immigrant status is called a 'change of status' and applied for on form I-539. However, changing to a permanent resident category from B-1/B-2 status, if immediately eligible, is applied for under INA 245a 'adjustment of status' on form I-485. An example of this would be a subsequent to entry marriage to an American citizen. There are many more complexities here, including priority dates, visa petition requirements, maintaining status, but the main concept underlying all of this is that adjustment of status is discretionary - and with few exceptions, marriage to a U.S. citizen being one, one must be 'in status' when the application is made.

How can one go from an F1 visa to permanent residency in America?

OPT ( Optional Practical Training) is the first logical step for a F1 visa student. OPT is a temporary employment designed  to give foreign student an opportunity to further their education in US. The student can file an Employment Authorization Document (EAD) . If approved he will be issued EAD. Student starts working after EAD is issued. Many employers file H1B petitions on behalf of F1 students. However H1B visas are under annual cap. If approved change of status can be obtained from F1 to H1B. STEM recognised students can apply for extension, if they donot get HIB under lottery,  by another 17 months. So totally they get 29 months under OPT. Next step is the employment based Green Card. Green card holders are non-US Citizens who have been authorised to live and work permanently in US. H1B visas are normally for a period of 6 years, given in 3 years installments.  Employers will opt to file green card for the employees who are working under H1B.Getting a green card is a multiple step process and it may take several years and it can be extremely frustrating.
