HELP : Migrant worker maintenance loan: when should I apply ??

Hello,

So I’ve been in the UK since early July now, I’ve been looking for a work but with Covid it was really hard for me to get one. So I started working mid august as a (self employed) and early September as an employed. My course start in November, I do have proof that I was in the UK on 1st September ( plane tickets, bank statement, ... ) so that’s fine. But the thing is that I will only get 3 months of payslips early December, so my question is, should I wait December to send my Student Finance application for tuition fee and maintenance loan as a migrant worker ? Wouldn’t that be too late ? And also I’m a EU citizens so will I have any problems with SF due to Brexit ?

Please help me because I really don’t know what to do. I’m scared that if I send my application too soon it won’t be accepted because I don’t have 3 months of payslips or even the P60,P45 documents

Thanks in advance for your answers
