The United States is a major immigrant nation, attracting numerous overseas individuals to settle, study, and work. There are many ways to immigrate to the U.S., among which family reunification is a popular choice. Today, we will provide a detailed analysis of family reunification immigration.
1. Differences between children of U.S. citizen immediate relatives and unmarried children of U.S. citizens under the first preference category, and the differences in application procedures
According to U.S. immigration law, immediate relatives of a U.S. citizen include the spouse, children, and parents of the U.S. citizen. A child qualifying as an immediate relative of a U.S. citizen must be unmarried and under the age of 21. Currently, while there are quotas for immediate relatives of U.S. citizens applying for immigration, the supply is ample, and there is no need to wait for a visa. The first preference category for unmarried children of U.S. citizens refers to those who are over 21 years of age. Individuals who are married or over 21 years old do not qualify as immediate relatives of a U.S. citizen and must wait in line according to the immigration preference categories when applying for U.S. immigration.
2. Differences between children born of a legal marriage and legitimate children under immigration law
A child born to parents in a legal marriage who is under 21 and unmarried is considered a child of a legal marriage. As long as the child is born of a legal marriage, when the parents apply to immigrate to the U.S. and the visa is approved, the child may immigrate to the U.S. with the parents upon their first entry, provided the child is under 21 and unmarried. Legitimate children refer to those born of a legal marriage who are already over 21 or married; such individuals must apply through the immigration preference category queue if they wish to immigrate to the U.S. Therefore, to immigrate with parents as a child, two prerequisites must be met: being under 21 and being unmarried; both are essential.
3. Stepchildren can immigrate with their new parents
Stepchildren refer to children who become stepchildren of a new spouse through the remarriage of one of their biological parents. If there is no marriage contract between the parent and the new spouse, and the step-relationship is not established through marriage, then no legal stepchild relationship exists. If the new spouse of the father or mother is a U.S. citizen or a U.S. permanent resident, the child can immigrate to the U.S. with the remarried parent, provided the child is under 21 and unmarried.
4. How to prove no intent to immigrate to the U.S. when applying for a non-immigrant visa?
Various non-immigrant visas involve the issue of whether there is an immigrant intent, and one must clearly prove the absence of such intent to obtain a visa. Generally, information such as whether a spouse and children remain in the home country, whether there is stable employment after returning, whether there is a stable economic foundation or savings in the home country, whether one owns a home domestically, and whether the itinerary in the U.S. includes a return date can all be used to prove the absence of immigrant intent.
5. Can short-term non-immigrant visas be extended?
With the exception of certain specific visas, non-immigrant visas can generally be extended, but there is a maximum validity period. The maximum validity varies by visa type; for example, B-category visas are generally granted for 6 months upon entry, which can then be extended up to one year, and so on.
6. How to apply for a visa extension? What supporting documents are required?
When applying for a visa extension or change of status, one must complete Form I-539 (Application to Extend/Change Nonimmigrant Status) and submit it to the USCIS between 15 and 60 days before the original visa expires. At the same time, the reason for the extension or change must be explained, and relevant documentation must be provided to the USCIS. Examples include letters from schools explaining the reason for the extension, or letters from project sponsors.
7. Non-immigrant visa validity periods vary, and the duration of stay in the U.S. for visa holders differs
The validity of a visa is determined by the individual's purpose for coming to the U.S. and the activities they will conduct. Generally, the tasks one intends to perform in the U.S. can be completed within the visa's validity period. For example, visitors on a family visit visa have 6 months, which can be extended up to one year to visit relatives and friends; those on business trips also have one year to handle affairs; the duration of a student visa mainly depends on the time required for the course of study.
8. Does having a visa guarantee legal stay in the U.S.? Each visa has its own specific purpose
After entry, visa holders who comply with U.S. law and engage in activities according to the purpose and plan of their visa have the right to stay legally in the U.S. for the duration of the visa's validity. However, if a visa holder engages in activities outside the scope of their visa during its validity period, they may be subject to arrest, fines, or deportation if discovered by the immigration authorities.
