You need 60 transferable units minimum to transfer. There is also a maximum, but it really doesn’t really apply if you have yet to take upper division units (Courses designated with numbers 300+) at UNR.
Unfortunately it’s not quite that easy. Renouncing your ties to Nevada and having your biological brother as a resident are huge for meeting the requirements, but it’s not quite foolproof. Your biggest issue will be showing a viable reason (that doesn’t include education at all) for the sudden change from living with your brother to moving with your dad. Regardless, you definitely have to relinquish your dependent status with your brother as residency is approved using federal markers such as taxes.

Prior to meeting with your DeAnza counselor, I suggest compiling as many of the course syllabi as you can get from your past and current UNR courses as they will make any placement and transfer ability questions much easier to answer. Additionally it helps to look at the [Assist.org Transfer Articulation Agreement](http://web2.assist.org/web-assist/report.do?agreement=aa&reportPath=REPORT_2&reportScript=Rep2.pl&event=19&dir=1&sia=DAC&ria=UCSC&ia=DAC&oia=UCSC&aay=14-15&ay=15-16&dora=CMPS) to get a better idea of your time frame and a list of courses you need to transfer.
