With the pending I-130, you are not likely to get a new student visa or tourist visa since the filing of the I-130 shows that you have immigrant intent even though you would not be eligible to immigrate on the basis of this petition for about 10-12 years.  You really should have either FIRST gotten a new visa and THEN had your sibling file on your behalf or not go outside the US and simply change your status within the US, if you are able to.  GOing outside the US will significantly increase your chances of denial of a new student visa.
