回复：Thanks very much Mr 863211, couple more questions:

my parents just got their green card, should my brother wait for another 5 years when my parents become citizens to be petition for my brother or ahould I petition for him right now? which way he will wait less years?

-You had better do it now and it will be faster.

My hu*****and and I own a small business, can we sponsor my brother's H-1b? what are the requirements?

-The job has to be in "specialty occupations" and the H-1B holder has to have bachelor degree or above.The regulations define a "specialty occupation" as requiring theoretical and practical application of a body of highly specialized knowledge in a field of human endeavor including but not limited to architecture, engineering, mathematics, physical sciences, social sciences, biotechnology, medicine and health, education, law, accounting, business specialties, theology, and the arts.
