tengo una hermana estado estadounidense

Tu hermana debe tramitar la I-130 y tu debes esperar en Venezuela. NO PUEDES «vivir» dentro de Estados Unidos.

Can my relative wait in the United States until becoming a permanent resident?

No. If your relative is outside the United States, filing an I-130 does
not allow your relative to live or work in the United States. An I-130
petition only establishes your relationship with your relative. Your
relative should wait outside the United States to immigrate legally.
If your husband or wife, unmarried child under 21 years, or parent
is already in the United States after having entered legally, they can
apply to adjust their status to permanent resident at the same time
you file their I-130 petition.

He leido que ese proceso puede tomar varios a#os. No es rapido.
