Definition of a Sibling
A sibling is a brother, sister, stepbrother, stepsister, or adopted
brother or sister. For the necessary sibling relationship to exist,
each person must have been a child of at least one of the same parents.
The siblings need not share the same biological parents as long as both
became "children" at the appropriate time (before the age of 16 in
cases of adoption, and before the age of 18 for stepchildren).
Overview
of the Immigration Process
A legal immigrant (or "lawful permanent resident") is a foreign national
who has been granted the privilege of living and working permanently in
the United States. There is a three-step process for your brother or
sister to become a legal immigrant:
- The USCIS must approve an immigrant
visa petition that you file for your brother or sister.
- The State Department visa bulletin must show that a sibling
immigrant visa is available to your sibling, based on the date that you
filed the immigrant visa application.
- If your brother or sister is outside the United States when an
immigrant visa number becomes available, your brother or sister will be
notified to go to the local U.S. consulate to complete the processing
for an immigrant visa. If your sibling is legally inside the U.S. when
an immigrant visa number becomes available, he or she may apply to
adjust status to that of a lawful permanent resident using the Form
I-485.
Depending on the relationship and the
country involved, the wait for an available sibling visa number may be
several years. You may refer to the Department
of State's Visa Bulletin for current priority dates.
For an excellent overview of
immigration, please see the chapter and tables on immigrants in the Immigration
Statistical Yearbook. For more information on immigrant visa
numbers, please see How Do I Get an

What Does
the Law Say?

of all immigrants to the United States. For the part of the law
concerning immigrant visas for siblings, please see INA § 203 and INA § 204. The
specific eligibility requirements and procedures for applying for
immigrant visas and permanent residence are included in the Code of
Federal Regulations [CFR] at 8 CFR § 204.1, 8
