Final answer:
Amelia can obtain H-4 visas for her spouse and young children as dependents of her H-1B visa. Broader U.S. immigration policies focusing on family immigration and skilled workers may impact green card allocations, but are separate from the H-1B and H-4 visa processes.
Step-by-step explanation:
Amelia, who has obtained an H-1B visa to work in the United States, will not need to obtain separate H-1B visas for her spouse and young children. Instead, her family members may apply for H-4 visas as dependents of an H-1B visa holder. The H-4 visa allows immediate family members which include spouses and children under the age of 21, to live and study in the U.S. but generally does not permit them to work unless they qualify for a work permit under certain conditions.
In the broader context of U.S. immigration policy, family-based immigration has been subject to significant debate. Policies have sought to balance various objectives such as family reunification and economic contribution. Currently, there is consideration to end extended-family chain migration and establish a points-based system focusing on high-skilled workers which would affect how green cards are allocated.
When it comes to family-based immigration, U.S. citizens usually get priority when petitioning to bring their family members to the country permanently. This is separate from the H-1B and H-4 visa process which is employment-based and non-immigrant in nature.
