i really want to thank you all for caring and giving me advise. i'm sorry for confusion if i caused so i want to summurize everything again. i hope i'm clear now.
if you can read it again, give me advise, i would really appriciate. i can explain more if you need to know details.
1 - i'm 24 year old spanish citizen and i went to us embassy to get F1 visa to get my masters at northeastern uni in boston. (masters in criminal justice)
2 - school gave me conditional acceptance because my toefl score was low. condition was to come to boston, finish language school(SCHOOL A) (different than northerstearn, but their partner) and start my program next year. When i went to embassy, the condition was there so i didn't lie or hide it.
3 - i arrived boston last year(10 days before my class starts). their tution increased a lot, cost of living in boston was more than i guessed so i decided it would cost so much and i wanted to find cheaper option for just language school.
4 - i researched and found a school in chicago. went to my friends place who went to this school. this school (SCHOOL B) was cheaper, i also found a roommate for a lot less price.
5 - i contacted SCHOOL A to transfer me to SCHOOL B. They did it. I got A NEW I-20 from SCHOOL B.
6 - i have no way of checking transfer process, i just asked my school "if everything is fine" they said "fine you are good"
7 - I went to SCHOOL B for 9 months. no issues. learned a lot. getting ready to take toefl again.
8 - Had to move back to spain for 2 months. i spent a month in spain to find sponsor. now i have it. SCHOOL B gave me a new I20 before leaving us.
9 - now i have valid F1 visa with SCHOOL A, and I20 from SCHOOL B.
10 - I read it is fine(having f1 visa from another school) and very common to re-enter in this case, but i want to ask you guys. i also read i don't need a new visa.
I really didn't make any illegal move or mistakes without knowing but i'm dealing with a system i don't know well and im worried something can be missed in all of this.
i was told many students change school, nobody care as long as you have valid visa and valid i20 document and valid student status. now i get different views which makes me worry.
thanks again, thank you a lot.
