i've applied for many jobs in the past while
how commonly do they ask you to fill a W-4? because this is the first time unless it's just been masked in digital forms
so in this packet, there's a normal application that's everything i'm used to, but then there's also an IRS form W4, ...and in the back, USCIS form I-9 for employment eligibility verification
for... a part time job as a cashier at the antique mall
