Namaste.

I am going to join new company(direct hire) and need to transfer my H1 from my current (direct hire). For this process I need last 3 months paycheck but in september I took whole month unpaid leave and do not have paystub. What should I do now?

Looking for suggestions.

 Well Since you require last 3 months,get the last three months...and explain why you took unpaid leave
or  idk I might sound smartass.......may be your last  3 months without break.....

I'm referring old company below as the company that you are leaving.

• Talk to your lawyer of the old company and/or new company. In general, your new hiring company should take care of these stuff and will guide you through it. There is always an exception and lwayers know how to deal with it.
  
• Provide the pay stub of the month before your unpaid leave ( if applicable)
• Provide your documents reflecting your unpaid leave. You might get this from your old company.
