I sent my UC transcript on July 1st but it says it has not been received, will I get rescinded?

The UC admissions site states that

“Deadline for admitted transfer students to submit Statement of Intent to Register (SIR). For students admitted for fall 2016: Final, official transcripts must be sent to the campus admissions office. Transcripts must be postmarked or electronically submitted on or before July 1.”

I submitted my transcript through Parchment on July 1st but the myUCR says that they have no yet received it, and I am really worried now. It says that Failure to meet this deadline will result in your admission being cancelled.

Will my admissions be rescinded?

Sometimes it takes a couple of weeks to process. I would check next week on their status.
