quite confused!bout NCLEX-RN,VSC

i applied in California to give me an approval to take NCLEX-RN Exam. now i am waiting for their eligibility.(is that a letter that i will receive from the CA board of nursing?) or is that what we call "ATT" authorization to test? after that am i now able to set an appointment to pearsonvue to schedule an exam?

after i pass the NCLEX then i need to pass also IELTS then apply for VisaScreen Certificate?then what's next? find an employer that will petition/sponsor me for I-140 type of visa?

this is the process that i know, am i right?? thank you so much
