Please I depend on my brother for my health and he just got a visa to travel to the US, can get join him?

Determine the type of visa your brother has and if it allows family members to join him.

You may be eligible for a derivative visa or a family-based visa.

File the required application and supporting documents.

Your brother may need to sponsor you or provide an affidavit of support.

Discuss your specific situation with an immigration attorney to determine the best course of action.
