Are there any differences in the physical presence requirements for the principal applicants and for dependents in an EB-5 case?

Yes, as lawful permanent residents both the principal and dependents have the same physical presence requirements to maintain permanent residence in the U.S.

The principal applicants and their dependents have the same set of obligations to reside in the U.S. The residency obligations are not transferable between the two groups. Each person, regardless of whether he/she is a principal or dependent, must meet his/her own residency requirements.

There is no difference. Each conditional permanent resident must meet the physical presence requirement for lawful permanent residents. If the conditional permanent resident plans to travel outside the United States for a long period of time, she/he may apply for a re-entry permit.

Once the conditional residence is granted, each person must maintain residency or get a reentry permit for an extended absence.

The principal applicant and the dependents are subject to the same requirements for physical presence in the U.S.

The physical presence requirements are the same for all green card holders except that derivative children are deemed to have the intent of their parents. USCIS is sometimes more lenient with minors attending school abroad.

The rules are the same for all.

Physical presence rules apply to all green card holders. Your dependants cannot meet the requirement for you.

All green card holders, including dependents, are subject to the same presence requirements as U.S. permanent residents. If they anticipate being absent for more than six months during any 12-month period, they should consult with their investment immigration attorney regarding a re-entry permit.

Each person''s green card is their own responsibility at that point. If the primary applicant really cannot or never planned to stay in the U.S., perhaps the investor should be another family member.

Those rules apply to all permanent residents. It makes no difference how they became permanent residents.
