Hey bryanna sorry but can i please ask few questions?An invitation letter signed by you addressed to the visa officer. You can scan and email it to your husband.
A visa request letter (cover letter) signed by your husband. It can have separate sections for Applicant details + UCI Number and PR app details + Purpose of Visit + Available funds for visit + Strong ties to Pakistan + Previous travel history (scan and include US visa in colour). All details must be short + point format (easy to read). Do give cross references to evidence
Ill probably apply online but if i end up applying paper based bcz of processing time ?can i sign and scan and email the letters from my side to my husband or i have to mail him the letters and docs from my side ?
And another question do everyone needs to fill the use of representative form?
