OK. Great. You don't have to have 3 pay stubs. You need to show sufficient current annual income which will be earned or continuing after relocation to the US. Current annual income is calculated as:
Gross income from most recent pay period multiplied times the number of pay periods per year (12 months).
Example: $2000 gross income every 2 weeks equals $52,000 (26 pay periods) current annual income.
Your evidence of US domicile looks good, imo.
