Pick a point you can justify from the cash schedule rather than from personal need. Many plans defer or reduce owner compensation until collections are established; others pay a modest amount from the start. Either can be defensible if the enterprise remains funded, operating, and capable of more than a minimal living.
Tie the draw to milestones you can evidence
Write the trigger into the plan: a signed lease, staff hired, doors open, a stated level of monthly collections. That gives a reviewer something concrete and gives you a decision rule when the month is tight. Keep in mind separately that a visa's validity period is not the same as the stay authorized on admission, and that the plan should reflect departure when status ends.
Consular officers test whether the enterprise is real and operating or will be on issuance. Identify what remains binding and what funds or resources are actually available.
