What's the difference between a green card and immigration?

Legal analysis: legal immigrants in the United States or their family members who have used public welfare benefits such as food stamps or "Chapter VIII housing subsidy coupons" may be refused a green card, aiming at reducing the burden on the state. In addition, the Trump administration is still raising the threshold for legal immigration, requiring married foreigners to apply for permanent residency, and there will be a minimum annual household income. Only those who meet the requirements and do not burden the public can hope to get a green card.

Legal basis: The US Department of Homeland Security will not accept the public burden.

Article 1 US visa applicant: Anyone who is applying for a visa will be refused if it is determined that it may become a burden to the public at any time;

Article 2 Anyone who applies for extension of residence in the United States or change of identity must prove that he has never used public welfare before and now, and will not bear public welfare in the future;

Article 3 Those who have applied for US green card status: When applying for legal residence status, the Immigration Bureau will have the right to decide whether the documents submitted by the applicant are sufficient to prove that they will not become a burden to the public.
