An individual who obtains an employment-based immigrant visa can become a Lawful Permanent Resident (LPR), also known as a Green Card holder, through an employment-based preference category.
Noncitizens physically present in the United States who seek to adjust their status to that of an LPR have to file Form I-485 based on a pending or approved immigrant visa petition, while noncitizens living abroad should submit an online Visa Application with DOS (Form DS-260) after approval of the immigrant visa petition.
The process generally begins with the adjudication of an immigrant visa petition filed on behalf of the noncitizen with USCIS For some categories, the process begins with the filing of a permanent labour certification application with the US Department of Labor (DOL).
The petition may be filed by a prospective employer, or in some cases, by the noncitizen on their own behalf (Source: uscis.gov).

Immigration Visa Set-Asides: Each fiscal year, a certain percentage of EB-5 immigrant visas are available to qualified immigrants who invest in specific areas: Rural areas: 20%; High Unemployment Areas: 10%; Infrastructure Projects: 2%.
Any of these set-aside visas that go unused are held in the same set-aside category for one more fiscal year. After the second fiscal year, any remaining new immigrant visas in these set-aside categories are released to the unreserved EB-5 immigrant visa numbers during the third fiscal year.
Taxation: All resident aliens (a resident alien is defined as a person who meets either the Green Card test or the substantial presence test for the calendar year) have to file income, estate, and gift tax returns and pay estimated tax.
The worldwide income of the individual/family is subject to US income tax the same way as it is for a US citizen.
In some cases, an alien can choose to be treated as a US resident alien. For example, if, at the end of the tax year, you are a resident alien and your spouse is a nonresident alien, the two of you can choose to treat the nonresident alien spouse as a US resident alien and file Form 1040 using the filing status married filing jointly.
