What are the requirements for applying for American spouse immigration?

So, what conditions does marriage immigration need to apply for? 1. Because this immigration application is based on marriage, marriage must be valid before applying for immigration. Applicants (American citizens or green card holders) must provide the marriage certificates of the applicant and the beneficiary when submitting their immigration applications to the Immigration Bureau. If one or both parties remarry, it is also necessary to provide proof that both parties have legally ended all marriages before. 2. In addition to the marriage certificate, other auxiliary materials are also reference objects. Such as: wedding photos or other family photos, proof of husband and wife's property lease, tax bill, proof that the spouse is the beneficiary of life insurance, house mortgage loan and common consumption loan, or a fine of 250,000 dollars. Foreigners with false marriage records may not apply for immigration to the United States on the grounds of marriage. 3/ Foreigners who apply for a green card through marriage can only get conditional permanent residency for two years. When applying for an immigrant visa, foreigners who have been legally married for two years can obtain formal permanent residency. If the marriage relationship is proved to be false within the two-year inspection period, or there is separation or divorce within two years, or the marriage relationship is proved to contain money disputes, the permanent residency of immigrants will be revoked and they will be deported. If there is no fake marriage during the two-year residence restriction period, both husband and wife can apply for permanent residence 90 days before the second anniversary of marriage, which shows that their marriage relationship is true. 4. After individual inquiries from immigration officials, we can further investigate the motivation and current situation of marriage. After examination, if the possibility of fake marriage is ruled out, immigration officials will lift the two-year limited residence restriction and give permanent residence certificates. When the marriage changes for other reasons than the immigrant's own reasons, the immigrant as a foreign spouse can file a complaint and be examined by the immigration officer. The reasons for the complaint that can be established are: I married my American spouse out of sincerity and affection, and the termination of the marriage was indeed justified; For example, after arriving in the United States, she is often abused by her husband. After spending a year in the United States, a foreign citizen filed for divorce and received a judgment. After careful investigation, immigration officials will waive her request for a two-year inspection period. On appeal, mental abuse is more difficult to prove than physical abuse. The following behaviors can be interpreted as mental abuse: withholding green cards, documents, money and controlling actions, and words such as "I won't let you see your relatives without listening to me" and "You can't go without a green card". Once abused, if you want to apply for exemption, it is best to seek the help of lawyers and psychologists. The Immigration Bureau trusts applicants represented by lawyers. 5. When foreigners apply for naturalization in the future, when calculating the actual residence time in the United States, the conditional residence period can be regarded as having formal permanent residency. Foreigners who have obtained permanent residency in the United States through marriage may not apply for spouse immigration for another foreigner because of remarriage within five years after obtaining formal permanent residency.
